Standard Guide for Abrasion Resistance of Mortar Surfaces Using a Rotary Platform Abraser

Standard Guide for Abrasion Resistance of Mortar Surfaces Using a Rotary Platform Abraser

SIGNIFICANCE AND USE
5.1 Wear on mortar surfaces can be generated by a number of factors including skidding, scraping or sliding of objects on the surface, foot and tire traffic. This guide provides a means to quantify the abrasion resistance of treated or untreated mortars and other similar products.
FIG. 1 Rotary Platform Abraser
FIG. 2 Arrangement of Rotary Platform Abraser Test Set-up  
5.1.1 This guide can be used to determine the effectiveness of fluid applied hardeners, densifiers and sealers by comparison with untreated control specimens.  
5.1.2 This guide can be used with other test methods to determine the effectiveness of surface treatments after abrasion. For example, Test Method D6532 can be used to evaluate the effectiveness of clear water repellents on hydraulic cement mortar specimens based on water absorption after water soaking, by testing the specimen prior to abrasion and after the specimen has been subjected to abrasion.  
5.2 This guide may be useful for acceptance testing of a mortar surface, and it can be used to evaluate the effects of processing variables such as substrate preparation before treatment, surface texture, treatment application variables, and curing regimen.  
5.3 Results may be used to correlate with in-place performance, for comparative rating of the performance of alternative materials, or for comparison among treated and untreated surfaces. The resistance of material surfaces to abrasion, as measured on a testing machine in the laboratory, is generally only one of several factors contributing to wear performance as experienced in the actual use of the material. Other factors may need to be considered in any calculation of predicted life from specific abrasion data.  
5.4 The resistance of mortar to abrasion may be affected by factors including test conditions, type of abradant, pressure between the specimen and abradant, selection of mortar-making materials (mixture proportions, curing and finishing procedures), and type, kind, or amo...
SCOPE
1.1 This guide is intended to assist in establishing procedures for determining the relative abrasion resistance of treated or untreated mortar surfaces.  
1.2 This guide utilizes the rotary platform abraser, which generates a combination of rolling and rubbing to cause wear to the specimen surface. Wear can be quantified as cycles to a specific end-point. Other commonly used evaluations are presented in Appendix X1 and include mass loss, wear index, volume loss, or depth of wear.  
1.3 The values stated either in SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. Some values have only SI units because the inch-pound equivalents are not used in practice.
Note 1: Other procedures used to measure abrasion resistance of concrete surfaces include Test Methods C418, C779/C779M, C944/C944M, and C1138M. Other methods that reference the rotary platform abraser and may be of interest include Specification C744 and Test Methods C1353, D4060 and F510.  
1.4 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM C1708/C1708M-23(Test Method)
Standard Test Methods for Self-leveling Mortars Containing Hydraulic Cements

SIGNIFICANCE AND USE
4.1 The test methods in this standard are used to evaluate freshly mixed properties such as the initial flow, flow retention, and healing time as well as hardened properties such as compressive strength, setting time, and flexural strength, of self-leveling mortars.  
4.2 Tests are conducted under standardized conditions for comparative purposes and results are not intended to be representative of performance under field conditions.
SCOPE
1.1 These test methods are appropriate to evaluate the performance of self-leveling mortars containing hydraulic cements that are used to improve the levelness, smoothness, and flatness of existing floors. These materials may be used as an underlayment to receive floor finishes, or as an overlayment to serve as the wear surface. The self-leveling mortars covered by these test methods consist of proprietary blends of hydraulic cements, along with fine aggregate, polymers, fillers, and other additives.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.)2  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM C1064/C1064M-23(Test Method)
Standard Test Method for Temperature of Freshly Mixed Hydraulic-Cement Concrete

SIGNIFICANCE AND USE
4.1 This test method provides a means for measuring the temperature of freshly mixed concrete. The measured temperature represents the temperature at the time of testing and may not be an indication of the temperature of the freshly mixed concrete at a later time. It may be used to verify conformance to a specified requirement for temperature of concrete.  
4.2 Concrete containing aggregate of a nominal maximum size greater than 75 mm [3 in.] may require up to 20 min for the transfer of heat from aggregate to mortar. (See ACI Committee 207.1R Report.4)
SCOPE
1.1 This test method covers the determination of temperature of freshly mixed hydraulic-cement concrete.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

ASTM C1876-23(Test Method)
Standard Test Method for Bulk Electrical Resistivity or Bulk Conductivity of Concrete

SIGNIFICANCE AND USE
5.1 The electrical resistivity of a concrete is the opposition to the movement of ions under an applied electric field. The electrical conductivity of a concrete is a measure of how readily the ions in the pore solution can be transported through the concrete under an applied electric field (the higher the conductivity, the greater the rate of transport). The electrical resistivity or conductivity is a material property that depends upon the pore volume, the pore structure (size and connectivity), the pore solution composition, the degree of saturation of the concrete specimen, and the specimen’s temperature. Concrete mixture characteristics that are known to affect concrete electrical resistivity, as well as resistance to chloride ion penetration, include water-cementitious materials ratio, pozzolans, slag cement, the presence of polymeric admixtures, air-entrainment, aggregate type, aggregate volume fraction, degree of consolidation, curing method, and age.  
5.2 The bulk electrical resistivity of concrete is the inverse of its bulk electrical conductivity. Bulk electrical conductivity can also be measured by Test Method C1760, which uses the apparatus described in Test Method C1202. This test method, however, uses apparatus specifically designed to measure bulk conductivity or bulk resistivity.  
5.3 The purpose of conditioning in a simulated pore solution is to bring the specimen to a level of near complete saturation of the capillary and gel pores. When comparing two different concrete specimens, it is important to condition both specimens as close as possible to a comparable saturation state, using the same solution for conditioning, so that values can be compared in a meaningful way. This is particularly true for using the measured resistivity or conductivity, along with other information, to estimate the diffusivity.  
5.4 The bulk electrical resistivity or conductivity of concrete can provide a rapid indication of its resistance to chloride ion penetrati...
SCOPE
1.1 This test method covers the determination of the bulk electrical resistivity or conductivity of molded specimens or cored sections of hardened concrete after immersion in water saturated with a simulated pore solution in order to provide a rapid indication of its resistance to the penetration of fluids and dissolved aggressive ions.  
1.2 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. If required results obtained from another standard are not reported in the same system of units as used by this standard, it is permitted to convert those results using the conversion factors found in the SI Quick Reference Guide.2  
1.3 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.)3 For specific warning statement see 8.1.2.

ASTM C1260-23(Test Method)
Standard Test Method for Potential Alkali Reactivity of Aggregates (Mortar-Bar Method)

SIGNIFICANCE AND USE
4.1 This test method provides a means of detecting the potential of an aggregate intended for use in concrete for undergoing alkali-silica reaction resulting in potentially deleterious internal expansion. It is based on the NBRI Accelerated Test Method (1-4).3 It is especially useful for aggregates that react slowly or produce expansion late in the reaction. However, it does not evaluate combinations of aggregates with cementitious materials nor are the test conditions representative of those encountered by concrete in service.  
4.2 Because the specimens are exposed to a NaOH solution, the alkali content of the cement is not a significant factor in affecting expansions.  
4.3 Results of tests conducted on an aggregate as described herein should form a part of the basis for a decision as to whether precautions should be taken against excessive expansion due to alkali-silica reaction. Refer to Guide C1778 for the interpretation of the test results from Test Method C1260.
SCOPE
1.1 This test method permits detection, within 16 days, of the potential for deleterious alkali-silica reaction of aggregate in mortar bars.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. When this test method refers to combined-unit standards, the selection of the measurement systems is at the user’s discretion.  
1.3 The text of this test method refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this test method.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific precautionary statement is given in the section on Reagents.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM C1810/C1810M-23(Guide)
Standard Guide for Comparing Performance of Concrete-Making Materials Using Mortar Mixtures

SIGNIFICANCE AND USE
4.1 The results of mortar mixture tests can be suitable for comparing the relative performance of combinations of concrete-making materials such as fine aggregate, chemical admixtures, supplementary cementitious materials (SCMs), water, and hydraulic cement. Furthermore, this guide can be useful to identify unexpected performances due to combination of various materials. The relative trends in performance observed with the mortar method may suggest relative performance in concrete mixtures batched with the same materials and relative mixture proportions.  
4.2 While there are a number of ways to proportion and mix mortar mixtures, four procedures described in this guide have been used extensively for evaluating the performance of admixtures. Method A enables evaluation of materials using mixture proportions that correspond to specific job conditions. Method B can be used as a general mixture using fixed amounts of a standard sand, cement, and supplementary cementitious materials. Method C is a modified version of Test Method C359 to evaluate the impact of chemical admixtures on the early stiffening of a mortar prepared with specified amounts of job cement, a standard sand, and an amount of water that will produce a mortar with a specified initial penetration measured in accordance with Test Method C359. The measurements of penetration over time can be related to the early stiffening processes associated with false and flash set. Method D is a modified version of Test Method C185 whereby the mortar mixture can be prepared with various combinations of chemical admixtures, supplementary cementitious materials, and job water. Methods A and B would be most applicable for investigating material incompatibility issues associated with ready mixed concrete, while Method C would be applicable for concrete mixed for a short period of time in stationary mixers and transported to the forms in non-agitating equipment. Method D is suitable for all concrete mixing processes and is...
SCOPE
1.1 This guide provides information on how to compare the relative performance and potential incompatibility of combinations of concrete-making materials. Performance tests on fresh and early-age properties of mortar mixtures can be useful indicators of concrete performance using similar materials. The performance tests described in this guide include mortar-slump, mortar spread, mortar-workability retention, early stiffening of mortar, time of setting, air entrainment, and hydration kinetics.  
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with this guide. Some values only have SI units because the inch-pound equivalents are not used in guide.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Warning—Fresh hydraulic cementitious mixtures are caustic and may cause burns to skin and tissue upon prolonged exposure.2  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM
ASTM C1090/C1090M-23(Test Method)
Standard Test Method for Measuring Changes in Height of Cylindrical Specimens of Hydraulic-Cement Grout

SIGNIFICANCE AND USE
4.1 This test method is intended to provide a means of assessing the ability of a hydraulic-cement grout to retain a stable volume during the stipulated testing period of 28 days, provided that the tendency to change height does not include the effects of drying caused by evaporation, uptake of moisture, carbonation, or exposure to temperatures outside the range 23.0 °C ± 2.0 °C [73 °F ± 3.5 °F] (Note 2). An exception is made when the options described in the section on test conditions are exercised.  
Note 2: This test method does not measure the change in height before setting (see Test Method C827/C827M).
SCOPE
1.1 This test method covers measurement of the changes in height of hydraulic-cement grout by the use of 75 mm by 150 mm [3 in. by 6 in.] cylinders, when the cylinders are protected so that the tendency to change in height does not include evaporation so as to cause drying, uptake of moisture, carbonation, or exposure to temperatures outside the range 23 °C ± 2.0 °C [73 °F ± 3.5 °F] or, optionally, to another specified temperature controlled within ±2.0 °C [±3.5 °F].  
1.2 If desired, this test method can be adapted to studies of changes in height involving either schedules or environmental treatment different from the standard procedures prescribed by this test method.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
Note 1: Sieve size is identified by its standard designation in Specification E11. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size.  
1.4 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to exposed skin and tissue upon prolonged exposure.2)  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Change in Height at Early Ages of Cylindrical Specimens of Cementitious Mixtures

SIGNIFICANCE AND USE
4.1 This test method provides a means for comparing the relative shrinkage or expansion of cementitious mixtures. It is particularly applicable to grouting, patching, and form-filling operations where the objective is to completely fill a cavity or other defined space with a freshly mixed cementitious mixture that will continue to fill the same space at time of hardening. It would be appropriate to use this test method as a basis for prescribing mixtures having restricted or specified volume change before the mixture becomes hard.  
4.2 This test method can be used for research purposes to provide information on volume changes taking place in cementitious mixtures between the time just after mixing and the time of hardening. However, the specimen used in this test method is not completely unrestrained so that the measurements are primarily useful for comparative purposes rather than as absolute values. Further, the degree of restraint to which the specimen is subjected varies with the viscosity and degree of hardening of the mixture.
SCOPE
1.1 This test method covers the determination of change in height of cylindrical specimens from the time of molding until the mixture is hard.  
1.2 This test method covers height change measurements at early ages for cementitious mixtures of paste, grout, mortar, and concrete.  
1.3 This test method is intended for determination of changes in height that occur from the time of placement until the specimen is fully hard. These include shrinkage or expansion due to hydration, settlement, evaporation, and other physical and chemical effects.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined  
1.5 The text of this test method refers to notes and footnotes that provide explanatory information. These notes and footnotes shall not be considered as requirements of the test method.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to exposed skin and tissue upon prolonged exposure.2)  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Effect of Organic Impurities in Fine Aggregate on Strength of Mortar

SIGNIFICANCE AND USE
5.1 This test method is of significance in making a final determination of the acceptability of fine aggregates with respect to the requirements of Specification C33/C33M concerning organic impurities.  
5.2 This test method is applicable to those samples which, when tested in accordance with Test MethodC40/C40M, have produced a supernatant liquid with a color darker than the standard listed in Table 1 of C40/C40M (Organic plate No. 3, Gardner Color Standard No. 14, Circular Disk No. 14 or prepared color solution).  
5.3 Many specifications provide for the acceptance of fine aggregate producing a darker color in the Test Method C40/C40M test, if testing by this test method indicates the strength of the mortar cubes prepared with the unwashed fine aggregate is comparable to the strength of mortar cubes made with the washed fine aggregate.
SCOPE
1.1 This test method covers the determination of the effect on mortar strength of the organic impurities in fine aggregate, whose presence is indicated using Test Method C40/C40M. Comparison is made between compressive strengths of mortar made with washed and unwashed fine aggregate.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Some values have only SI units because the inch-pound equivalents are not used in the practice.
Note 1: Sieve size is identified by its standard designation in Specification E11. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.(Warning—Fresh hydraulic cementitous mixtures are caustic and may cause chemical burns to exposed skin and tissue upon prolonged exposure.)2

Standard Specification for Packaged, Dry, Combined Materials for Concrete and High Strength Mortar

ABSTRACT
This specification covers the production, properties, packaging, and testing of packaged, dry, combined materials for concrete and mortars. Concrete mixtures covered by this specification includes high-early strength concrete, normal strength concrete, normal weight concrete, high-strength mortar, and mortars for unit masonry. The purchaser shall specify the material desired as concrete, high strength mortar, or mortar for use with unit masonry, and the respective physical requirements. Materials used as ingredients in packaged, dry, combined materials for mortar and concrete shall be composed of aggregates, air-entraining admixtures, blended cement, chemical admixtures, fly ash, ground granulated blast-furnace slag, hydrated lime, latex and powder polymer modifiers, masonry cement, mortar cement, Portland cement, and silica fume. All aggregates shall be dried, without disintegration, to specific moisture content The proportions of cementitious material and aggregate shall be such that the strength requirements will be met. Packaged, dry, combined materials for concrete, high strength mortar and mortar for use with unit masonry shall conform to the respective compressive strength requirements. Scales conforming to the standards will be used for sampling concretes from a single batch using a sufficient quantity. A slump test will be performed to check if additional water is required. In sampling mortar, the contents of an entire package of dry, combined material for mortar for unit masonry or for concrete mortar shall be used. Mortar mixing equipment, which must be provided with a bowl positioning adapter, shall be used to ensure clearance for the largest size aggregate in the mix being tested. The specification includes the following testing methods for mortar: compressive strength, density and yield, air content, and water retention.
SCOPE
1.1 This specification covers the production, properties, packaging, and testing of packaged, dry, combined materials for concrete and high strength mortar. The classifications of concrete and mortar covered are defined in Section 3.
Note 1: The scope of this standard does not cover mortars for unit masonry. Dry preblended mortars for unit masonry are covered by Specification C1714/C1714M.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Some values have only SI units because the inch-pound equivalents are not used in practice.  
1.3 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.  
1.4 The following safety hazards caveat pertains only to the test method portion of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Measuring Hydration Kinetics of Hydraulic Cementitious Mixtures Using Isothermal Calorimetry

SIGNIFICANCE AND USE
5.1 Thermal power curves are used to evaluate the isothermal hydration kinetics of the combined mixture of different materials during the early period after being mixed with water. These isothermal power curves, or hydration profiles, may provide indications relative to setting characteristics, compatibility of different materials, sulfate balance and early strength development. The isothermal hydration profiles can also be used to evaluate the effects of compositions, proportions, and time of addition of materials as well as curing temperature. Special care must be used in evaluating extended retardation with paste specimens, which have been shown to overestimate the retardation of some mixtures containing cement, SCM, and admixtures.  
5.2 This procedure can be used to measure the effect of chemical admixtures on the cement hydration profile. In many cases, the addition of chemical admixture changes the kinetics of cement hydration.  
5.3 Although this technique has been used historically to understand issues related to setting and slump loss, it must be emphasized that isothermal calorimetry results cannot predict concrete performance definitely, either positively or negatively. Extensive verification in concrete at planned dosages and temperatures, and at higher dosages, is needed. Isothermal calorimetry is an effective tool to identify sensitivities, so that concrete testing can be efficiently planned and performed.  
5.4 This practice provides a means of assessing the relative hydration performance of various test mixtures compared with control mixtures that are prepared in a similar manner.  
5.5 The procedure and apparatus can be used to monitor the thermal power from pastes and mortars alone or in combination with chemical admixtures.  
5.6 The isothermal calorimeter described here can be used to measure the thermal power and heat of hydration of mortars prepared independently or obtained by wet sieving from concrete in accordance with Practice C172/C1...
SCOPE
1.1 This practice describes the apparatus and procedure for measuring relative differences in hydration kinetics of hydraulic cementitious mixtures, either in paste or mortar (see Note 1), including those containing admixtures, various supplementary cementitious materials (SCM), and other fine materials by measuring the thermal power using an isothermal calorimeter.
Note 1: Paste specimens are often preferred for mechanistic research when details of individual reaction peaks are important or for particular calorimetry configurations. Mortar specimens may give results that have better correlation with concrete setting and early strength development and are often preferred to evaluate different mixture proportions for concrete. Both paste and mortar studies have been found to be effective in evaluating concrete field problems due to incompatibility of materials used in concrete mixtures.  
1.2 This practice does not cover the measurement of heat of hydration. Heat of hydration can be determined according to Test Method C1702.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2)  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
