Standard Test Method for Fineness of Hydraulic Cement and Raw Materials by the 300-μm (No. 50), 150-μm (No. 100), and 75-μm (No. 200) Sieves by Wet Methods

Standard Test Method for Fineness of Hydraulic Cement and Raw Materials by the 300-μm (No. 50), 150-μm (No. 100), and 75-μm (No. 200) Sieves by Wet Methods

ABSTRACT
This test method covers wet sieving techniques for determination of fineness of hydraulic cement and raw materials by means of the No. 50, No. 100, and No. 200 sieves. The following apparatus shall be utilized: wet test sieves; spray nozzle; pressure gage; balance; weights; brush; dry test sieves; and NBS SRM No. 1004 (glass bead standard). Dry sieve standardization shall be performed by determining the correction factors and by preparing the standard samples. Wet sieve calibration shall follow and shall utilize the sieve correction factor. The procedure for wet sieving shall include the following: weighing of the sample; recording the weight and transferring the sample quantitatively to a clean dry sieve; wetting the sample thoroughly with a gentle stream of water; removing the sieve from under the nozzle and adjusting the pressure of the spray nozzle; returning the sieve to its position under the nozzle and washing it; moving the sieve in the spray with a circular motion; rinsing the sieve with distilled or deionized water immediately after removing it from the spray; blotting the lower surface of the screen cloth with a damp, clean cloth; drying the sieve and residue in an oven or over a hot plate; cooling the sieve; brushing the residue from the sieve; and weighing the sieve on a balance.
SCOPE
1.1 This test method covers wet sieving techniques for determination of fineness of hydraulic cement and raw materials by means of the 300-μm (No. 50), the 150-μm (No. 100), and the 75-μm (No. 200) sieves.
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. Values in SI units [or inch-pound units] shall be obtained by measurement in SI units [or inch-pound units] or by appropriate conversion, using the Rules for Conversion and Rounding given in  of measurements made in other units. Values are stated in SI units when inch-pound units are not used in practice.
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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Drying Shrinkage of Mortar Containing Hydraulic Cement

SIGNIFICANCE AND USE
4.1 This test method establishes a selected set of conditions of temperature, relative humidity and rate of evaporation of the environment to which a mortar specimen of stated composition shall be subjected for a specified period of time during which its change in length is determined and designated “drying shrinkage.”  
4.2 The drying shrinkage of mortar as determined by this test method has a linear relation to the drying shrinkage of concrete made with the same cement and exposed to the same drying conditions.4 Hence this test method may be used when it is desired to develop data on the effect of a hydraulic cement on the drying shrinkage of concrete made with that cement.
SCOPE
1.1 This test method determines the change in length on drying of mortar bars containing hydraulic cement and graded standard sand.  
1.2 The values stated in SI units are to be regarded as standard. When combined standards are referenced, the selection of measurement system is at the user’s discretion subject to the requirements of the referenced standard.  
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 C114-23(Test Method)
Standard Test Methods for Chemical Analysis of Hydraulic Cement

ABSTRACT
These test methods cover the chemical analyses of hydraulic cements. Specific chemical test methods are grouped as reference test methods and alternative test methods. The reference test methods are long accepted classical chemical test methods which provide a reasonably well-integrated basic scheme of analysis for hydraulic cements and are also required for referee analysis in those cases where conformance to chemical specification requirements are questioned. Apparatus and materials for the test method include balance, weights, glassware and laboratory containers, desiccators, filter paper, crucibles, and muffle furnace. Standard reagents for the test method shall be used within the limits of the specification. These reagents shall include purity agents, water, repackaged reagents, concentrated acids and ammonium hydroxide, nonstandardized solutions, and indicator solutions. Sample preparation and general test procedures shall be followed according to the specification. General procedures include sample weighing, taring of crucibles, weighing of ignited residues, volatilization of platinum, chemical analyses, and calculation. Reporting of analyses shall be of the following order: major components, minor components, and separate determinations. Reference test methods and procedures include determination of insoluble residue, silicon dioxide, ammonium hydroxide group, ferric oxide, phosphorus pentoxide, titanium dioxide, zinc oxide, aluminum oxide, calcium oxide, magnesium oxide, sulfur, loss on ignition, sodium and potassium oxides, manganic oxide, chloride, chloroform-soluble organic substances. Alternative test methods and procedures include determination of calcium oxide, calcium dioxide, magnesium oxide, loss on ignition, titanium dioxide, phosphorus pentoxide, manganic oxide, and free calcium oxide. The standardization used for qualification and for analysis of each constituent shall be determined by valid curve-fitting procedures.
SCOPE
1.1 These test methods cover the chemical analyses of hydraulic cements. Any test methods of demonstrated acceptable precision and bias may be used for analysis of hydraulic cements, including analyses for referee and certification purposes, as explained in Section 4. Specific chemical test methods are provided for ease of reference for those desiring to use them. They are grouped as Reference Test Methods and Alternative Test Methods. The reference test methods are long accepted classical chemical test methods which provide a reasonably well-integrated basic scheme of analysis for hydraulic cements. The alternative test methods generally provide individual determination of specific analytes and may be used alone or as alternates and determinations within the basic scheme at the option of the analyst and as indicated in the individual method.

Standard Performance Specification for Hydraulic Cement

SCOPE
1.1 This performance specification covers hydraulic cements for both general and special applications. There are no restrictions on the composition of the cement or its constituents (see Note 1).
Note 1: There are two related hydraulic cement standards, Specification C150/C150M for portland cement and Specifications C595/C595M for blended cements, both of which contain prescriptive and performance requirements  
1.2 This performance specification classifies cements based on specific requirements for general use, high early strength, resistance to attack by sulfates, and heat of hydration. Optional requirements are provided for the property of low reactivity with alkali-silica-reactive aggregates and for air-entraining cements.  
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 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. Values in SI units [or inch-pound units] shall be obtained by measurement in SI units [or inch-pound units] or by appropriate conversion, using the Rules for Conversion and Rounding given in IEEE/ASTM SI 10, of measurements made in other units [or SI units]. Values are stated in only SI units when inch-pound units are not used in practice.  
1.4 The text of this performance specification refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) are not requirements of the 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.  
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 Specification for Blended Hydraulic Cements

ABSTRACT
This specification pertains to blended hydraulic cements for both general and special applications, using slag or pozzolan, or both, with portland cement or portland cement clinker or slag with lime. These cements are classified into two types: Type IS which is portland blast-furnace slag cement and Type IP which is portland-pozzolan cement. They can also be described according to air-entraining, moderate sulfate resistance, moderate heat of hydration, high sulfate resistance, or low heat of hydration properties. The cement shall conform to the chemical requirements prescribed. In addition, the cement shall undergo different tests to determine the following properties: chemical analysis, fineness by sieving, fineness by air-permeability, autoclave expansion, time of setting, air content of mortar, compressive strength, heat of hydration, normal consistency, specific gravity, water requirement, mortar expansions of blended cement and pozzolan, drying shrinkage, activity index with Portland cement, and sulfate resistance.
SCOPE
1.1 This specification pertains to blended hydraulic cements for both general and special applications, using slag, pozzolan, limestone, or some combination of these, with portland cement or portland cement clinker or slag with lime.
Note 1: This specification prescribes ingredients and proportions, with some performance requirements, whereas Performance Specification C1157/C1157M is a hydraulic cement specification in which performance criteria alone govern the products and their acceptance.  
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. Values in SI units [or inch-pound units] shall be obtained by measurement in SI units [or inch-pound units] or by appropriate conversion, using the Rules for Conversion and Rounding given in IEEE/ASTM SI 10, of measurements made in other units [or SI units]. Values are stated in only SI units when inch-pound units are not used in practice.  
1.3 The text of this specification refers to notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) are not requirements of the standard.  
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.

Standard Specification for Processing Additions for Use in the Manufacture of Hydraulic Cements

ABSTRACT
This specification covers the criteria and tests to be used for determining whether a processing addition meets the requirement. When proposed addition is accepted for general use in Portland cement, tests shall be made on cements prepared from at least five different clinkers. These clinkers shall represent two Type I cements, one Type II cement, and two Type III cements. Processing additions shall be evaluated by comparing cements containing the addition to otherwise identical cements from the same source without the addition, or containing a processing addition. The compressive strength and flexural strength of the concrete made with cement containing the addition shall be compared with strengths obtained with the control cement at similar ages. The properties of the materials shall be determined through the following tests in accordance with the following standard: chemical analysis of the cement, compound composition, fineness of cement, normal consistency, time of setting, autoclave expansion, air content of mortar, compressive strength of mortar, and drying shrinkage of mortar.

ASTM
ASTM C1910/C1910M-23(Test Method)
Standard Test Methods for Cements that Require Carbonation Curing

SIGNIFICANCE AND USE
4.1 These test methods are used to develop data for comparison with the requirements of Test Methods C1910/C1910M or other specifications for cements that require carbonation curing. These test methods are based on standardized testing in the laboratory and are not intended to simulate job conditions. All tests are performed with mortar and therefore, the results may not provide a direct correlation of how the tested cementitious material will perform in concrete.  
4.2 Compressive Strength—The test for compressive strength is used to determine whether the cement tested will develop a minimum level of strength when carbonated under laboratory conditions.  
4.3 Chemically Bound Carbon Dioxide—Determined using mortar cube specimens prepared for determining compressive strength, the test for chemically bound carbon dioxide is used as an estimate of the mass of carbon dioxide bound during the carbonation curing process and is expressed as a percent of the mass of cement in the test mixture. The actual amount of carbon dioxide bound in a manufactured product is affected by the carbonation process and the cement used, and the physical characteristics of the manufactured product.
SCOPE
1.1 These test methods cover procedures for testing cements that require carbonation curing and are intended for use in concrete.  
1.2 The procedures are organized in the following sections:    
Casting and Carbonation Curing Test Specimens  
Section 8  
Compressive Strength  
Section 9  
Bound Carbon Dioxide  
Section 10  
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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this standard. Some values only have SI units because the inch-pound equivalents are not used in standard.  
1.4 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, Annex A in Form and Style for ASTM Standards, www.astm.org/COMMIT/Blue_Book.pdf.  
1.5 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 the standard.  
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—Common cementitious mixtures are caustic and may cause burns to 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 Specification for Rapid Hardening Hydraulic Cement

ABSTRACT
This specification covers performance requirements for rapid hardening hydraulic cements. There are no restrictions on the compositions of the cement or its constituents. The specification classifies cements by type based on specific requirements for very early compressive strength development. The following are the four types of rapid hardening cement: (1) Type URH, ultra rapid hardening for use where high early strength is desired; (2) Type VRH, very rapid hardening for use where very high early strength is desired; (3) Type MRH, medium rapid hardening for use where mid-range hardening high early strength is desired; and (4) Type GRH, general rapid hardening for use when the higher strength properties of a Type VRH or a Type MRH cement is not required. Cement of the type specified shall conform to all of the applicable standard physical requirements for compressive strength and drying shrinkage. Cement shall be tested using the following methods: autoclave expansion; time of setting; compressive strength; drying shrinkage of mortar; heat of hydration; surface resistance; alkali silica resistivity; and expansion in water.
SCOPE
1.1 This specification is for rapid hardening hydraulic cements. This is a specification giving performance requirements. There are no restrictions on the composition of the cement or its constituents.  
1.2 The specification classifies cements by type based on specific requirements for very early compressive strength development.  
1.3 The values stated in either SI units or inch-pound units shall be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
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) are not requirements of the 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 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 Specification for Cements that Require Carbonation Curing

SCOPE
1.1 This specification covers cements that require controlled exposure to carbon dioxide to achieve strength, referred to as carbonation curing. These cements are for use in concrete that does not contain steel reinforcement. There are no restrictions on the constituents of the cement. The producer is required to demonstrate that carbon dioxide is chemically bound by the cement.  
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. Values are stated in only SI units when inch-pound units are not used in practice.  
1.3 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, Annex A in Form and Style for ASTM Standards, www.astm.org/COMMIT/Blue_Book.pdf.  
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) are not requirements of the 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.  
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.

ASTM C183/C183M-23(Practice)
Standard Practice for Sampling and the Amount of Testing of Hydraulic Cement

SIGNIFICANCE AND USE
4.1 The sampling procedures described are intended for use in the procurement of samples of hydraulic cement after it has been manufactured and is ready to be offered for sale. They are not intended as sampling procedures for quality control purposes during manufacturing. The testing procedures outlined cover the amount of testing to be done and provide guidance for reporting on conformance or non-conformance of cements with requirements of purchase specifications.  
4.2 This practice is referenced as the procedure for sampling natural cement (Specification C10/C10M), masonry cement (Specification C91/C91M), portland cement (Specification C150/C150M), blended hydraulic cement (Specification C595/C595M), expansive hydraulic cement (Specification C845/C845M), hydraulic cement based on a performance specification (Specification C1157/C1157M), plastic stucco cement (Specification C1328/C1328M), and mortar cement (Specification C1329/C1329M), and  
4.3 Most building codes and construction specifications require that hydraulic cement to be used in the work meet the applicable requirements of the relevant purchase specifications, such as Specifications C10/C10M, C91/C91M, C150/C150M, C595/C595M, C1157/C1157M, C1328/C1328M, C1329/C1329M, or C845/C845M. If the code or specification requires sampling of the manufactured cement, the provisions given in 4.4 are applicable. Not much cement is sold on the basis of such sampling and testing. A useful discussion of sampling and testing cement is contained in ACI 225.1R.  
4.4 The procedures covered in this practice should be done by or for purchasers of hydraulic cement who are using a code or specification that requires sampling and testing to determine if the samples conform to the relevant acceptance specifications. The testing is done using specified methods to determine whether the samples yield test results that conform to the specification, and the tests serve as a basis for acceptance or rejection of the lot of material ...
SCOPE
1.1 This practice covers procedures for sampling and for the amount of testing of hydraulic cement after it has been manufactured and is ready to be offered for sale.  
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. Values in SI units [or inch-pound units] shall be obtained by measurement in SI units [or inch-pound units] or by appropriate conversion, using the Rules for Conversion and Rounding given in Standard IEEE/ASTM SI 10, Values are stated in only SI units when inch-pound units are not used in practice  
1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered requirements of the 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.  
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.
