Standard Test Method for Alkali Resistance of Fiber Reinforced Polymer (FRP) Matrix Composite Bars used in Concrete Construction

Standard Test Method for Alkali Resistance of Fiber Reinforced Polymer (FRP) Matrix Composite Bars used in Concrete Construction

SIGNIFICANCE AND USE
5.1 This test method is intended to determine alkaline resistance data for material specifications, research and development, quality assurance, and structural design and analysis. Depending on the procedure and test matrix, the primary test results are the mass change and tensile capacity retention of the test specimen, which are important factors to be considered in the use of FRP reinforcing bars. Procedures A and B are accelerated tests, substituting an alkaline aqueous environment for the presence of concrete porewater. Procedure C can be used to establish the accelerating effect of Procedure B.  
5.1.1 Procedure A is appropriate for rapid screening of FRP bars for alkali resistance.  
5.1.2 Procedure B is appropriate for characterizing the alkali resistance of FRP bars under sustained mechanical loading in a standard aqueous alkaline environment intended to represent the concrete porewater.  
5.1.3 Procedure C is appropriate for characterizing the alkali resistance of FRP bars under sustained mechanical loading in Portland cement concrete.
SCOPE
1.1 This test method covers the procedure for evaluating the alkali resistance of FRP bars used as reinforcing bars in concrete. Alkali resistance is measured by subjecting the FRP bars to an aqueous alkali environment, with or without sustained tensile stress, and then testing them to failure in tension according to Test Method D7205/D7205M. This standard presents three procedures conducted at a moderately elevated temperature of 60 ºC (140 ºF), each defining different loading conditions. The test method is also appropriate for use with linear segments of FRP reinforcements cut from two- or three-dimensional reinforcing grid.  
1.2 The values stated in either inch-pound units or SI units shall be regarded separately as the standard. The inch-pound units are shown in the parentheses. The values stated in each system are not exact equivalents; therefore each system shall be used independently of each other. Combining values from the two systems may result in non-conformance.  
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.  
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 D7914/D7914M-21(Test Method)
Standard Test Method for Strength of Fiber Reinforced Polymer (FRP) Bent Bars in Bend Locations

SIGNIFICANCE AND USE
5.1 This test method is intended to determine the bend strength of FRP composite concrete reinforcements, developed at a standard twelve bar diameters of embedment. From this test, a variety of data are acquired that are needed for design purposes. Material-related factors that influence the tensile response of bars include the following: constituent materials, void content, volume percent reinforcement, methods of fabrication, and fiber reinforcement architecture. Similarly, factors relevant to the measured tensile response of bars include specimen preparation, specimen conditioning, environment of testing, specimen alignment, and speed of testing. The results may be used for material specifications, research and development, and structural design and analysis.
Note 1: Two FRP bends are tested simultaneously in this test method, but in some cases, only one bend may fail. While resulting in a valid failure, notice should be taken that only one bend has been effectively measured and that the final compiled test results using this method could differ from those resulting from single FRP bend testing.
SCOPE
1.1 This test method determines the quasi-static ultimate strength of fiber reinforced polymer (FRP) composite bent bars commonly used as anchorages for stirrups in reinforced, prestressed, or post-tensioned concrete structures. This test method only applies to bars with a solid cross section.  
1.2 FRP bent bars are often used in reinforced concrete applications to shorten the development length of the bar or to act as a tie or a stirrup to resist shear forces. Bent bars can be produced with varying angles of bend in order to fit their intended purpose.  
1.3 For this test method, the FRP bars are bent at a 90 degree angle. In general, bars have a regular pattern of surface undulations, a coating of bonded particles, or both, that promote mechanical interlock between the bar and concrete.  
1.4 This test method may be completed on standardized bars, produced according to Specification D7957/D7957M. In this case, the nominal cross-sectional areas and effective diameters are taken from D7957/D7957M. This test method may also be used for bars that are not standardized. In this case, the cross-sectional areas and effective diameters should be measured and calculated as described in Test Method D7205/D7205M.  
1.5 The strength values provided by this method are short-term, quasi-static tensile strengths that do not account for sustained static or cyclic loading. If bars are to be used under high levels of sustained or repeated loading, additional material characterization may be required.  
1.6 The characteristic values obtained from this test method are intended to represent the quasi-static ultimate strength of FRP bent bars with a tail length of twelve bar diameters.  
1.7 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 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.  
1.7.1 Within the text, the inch-pound units are shown in brackets.  
1.8 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.  
1.9 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 D7913/D7913M-14(2020)(Test Method)
Standard Test Method for Bond Strength of Fiber-Reinforced Polymer Matrix Composite Bars to Concrete by Pullout Testing

SIGNIFICANCE AND USE
5.1 The behavior of the bond between concrete and FRP reinforcing bars is an important performance aspect that has been used in material specifications and design standards. This test method serves as a means for uniformly preparing specimens and testing FRP bar-to-concrete bond, and for providing a standard method to calculate, evaluate and report bond strength.  
5.2 This test method for measuring bond strength by pullout testing is intended for use in laboratory tests in which the principal variable is the size or type of FRP bars.  
Note 1: This test method should not be used to establish design bond values and development lengths for FRP bars embedded in concrete, as it does not represent the state of bond stress observed in concrete flexural members reinforced with FRP bars. See Test Method A944 for a beam-end test configuration, used for determining bond stress in steel bars.  
5.3 This test method is intended to determine the bond behavior for material specifications, research and development. The bond behavior will be specimen-configuration dependent, which may affect both analysis and design. The primary test result is the bond strength of the specimen to normal weight concrete.  
5.4 This test method may also be used to determine the conformance of a product or a treatment to a requirement relating to its effect on the bond developed between FRP bar and concrete. The result obtained from this test method should be used only for comparative purposes to compare parameters or variables of bond strength. The method may be used as part of a protocol to establish long-term environmental effects on bond to concrete, including environmental reduction factors for FRP bars embedded in concrete.
SCOPE
1.1 This test method covers the determination of the bond strength of fiber-reinforced polymer (FRP) composite bars used as reinforcing bars or pre-stressing tendons in concrete.  
1.2 Two procedures for casting test specimens are provided. The first procedure aligns the bar with the concrete casting direction. The second procedure aligns the bar’s transverse to the concrete casting direction.  
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.  
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.

Standard Test Methods for Determining Effects of Chemical Admixtures on Corrosion of Embedded Steel Reinforcement in Concrete Exposed to Chloride Environments

SIGNIFICANCE AND USE
3.1 These test methods provide a reliable means for predicting the inhibiting or corrosive properties of admixtures to be used in concrete.  
3.2 The total integrated (coulombs) current is calculated to provide an indication of the corrosion that occurs due to the macrocell corrosion.  
3.3 These test methods are useful for development studies of corrosion inhibitors to be used in concrete.  
3.4 These test methods have been used elsewhere with good agreement between corrosion as measured by these test methods and corrosion damage on the embedded steel (1-4).4 These test methods might not properly rank the performance of different corrosion inhibitors, especially at concrete covers over the steel less than 40 mm (1.5 in.) or water-to-cement ratios above 0.45. The concrete mixture proportions and cover over the steel are chosen to accelerate chloride ingress. Some inhibitors might have an effect on this process, which could lead to results that would differ from what would be expected in actual use (5).
SCOPE
1.1 These test methods cover a procedure for determining the effects of chemical admixtures on the corrosion of metals in concrete. These test methods can be used to evaluate materials intended to inhibit chloride-induced corrosion of steel in concrete. It can also be used to evaluate the corrosivity of admixtures in a chloride environment.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered 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.

Standard Test Method for Measurement of Solids in Water

SIGNIFICANCE AND USE
4.1 This test method is used to determine the solids content of mixing water used to produce concrete when one or more of the water sources is wash water from concrete production operations or water that contains solids when batched as mixing water in concrete.  
4.2 The test method provides a means to determine the relationship between the density and solids content of water for compliance with solids content limits of mixing water such as in Specification C1602/C1602M.  
4.3 During production of concrete, the water property measured is its density, which can then be used to estimate the solids content from procedures described in this test method.  
4.4 To develop a correlation between the density and solids content of water, water samples should be tested that cover the range of solids concentrations anticipated during production.
SCOPE
1.1 This test method covers the measurement of the solids content in water for use as mixing water in ready-mixed concrete and the measurement of its density. Solids content is expressed in terms of parts per million (ppm) or in terms of percent by mass of the water sample.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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 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.

ASTM D7234-22(Test Method)
Standard Test Method for Pull-Off Strength of Coatings on Concrete Using Portable Pull-Off Adhesion Testers

SIGNIFICANCE AND USE
5.1 The pull-off strength and mode of failure of a coating from a concrete substrate are important performance properties that are used in specifications. This test method serves as a means for uniformly preparing and testing coated surfaces, and evaluating and reporting the results.  
5.2 Variations in strength results obtained using different instruments, different substrates, or different loading fixtures with the same coating are possible. Therefore, it is recommended that the specific test instrument and loading fixture be mutually agreed upon between the interested parties.  
5.3 It is recommended that the coating be sufficiently cured to ensure cohesive strength and adhesion. This required minimum cure time before testing should be provided by the coating manufacturer, and may require an extension due to atmospheric conditions on site (for example, low temperature, and low or high humidity).  
5.4 This test method may be adapted to determine surface strength of uncoated concrete (see X2.1). Test Method C1583 is also suitable for that determination.  
5.5 The objective of this method is to determine the adhesion of a coating to concrete (or adapted for surface strength as stated in 5.4) and will result in failure in the coating or near the substrate surface. If evaluating the cohesive strength of the substrate or cementitious surfacers is the purpose of the testing, or if the substrate or cementitious surfacers have low strength, then Test Method C1583 may be more suitable.
SCOPE
1.1 This test method covers procedures for evaluating the pull-off strength of a coating on concrete. Pull-Off strength of coatings for other rigid substrates is described in Test Method D4541. The test determines the greatest perpendicular force (in tension) that a surface area can bear before a plug of material is detached. Failure will occur along the weakest plane within the system comprised of the loading fixture, glue, coating system, and substrate, and will be exposed by the fracture surface.  
1.2 This test method uses a class of apparatus known as portable pull-off adhesion testers.2 They are capable of applying a concentric load and counter load to a single surface so that coatings can be tested even though only one side is accessible. Measurements are limited by the strength of adhesion bonds between the loading fixture, coating system and the substrate or the cohesive strengths of the glue, coating layers, and substrate.  
1.3 This test method is suitable for both laboratory and field testing.  
1.4 Pull-off strength measurements depend upon both material and instrumental parameters. There are different instruments used that comply with this test method. The specific instrument used should be identified when reporting results. This test is destructive and spot repairs may be necessary.  
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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.  
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.

SIGNIFICANCE AND USE
3.1 This test method is intended to determine the effects of freezing and thawing on units conforming to the dimensional requirements of Specification C936/C936M while immersed in a test solution. Other types of segmental concrete paving units that do not conform to the dimensional requirements of Specification C936/C936M may be tested using this test method.  
3.2 The results from this test method are not intended to provide a quantitative measure of the length of service from concrete paving units conforming to the dimensional requirements of Specification C936/C936M.
SCOPE
1.1 This test method evaluates the resistance to freezing and thawing of solid interlocking concrete paving units conforming to the dimensional requirements of Specification C936/C936M. Units are tested in a test solution that is either tap water or 3 % saline solution, depending on the intended use of the units in actual service.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered 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.

ASTM A1044/A1044M-22a(Specification)
Standard Specification for Steel Stud Assemblies for Shear Reinforcement of Concrete

SCOPE
1.1 This specification covers steel stud assemblies for shear reinforcement of concrete. Stud assemblies consist of either single-headed studs (Type 1) attached to a structural steel base rail by structural welding or stud welding, or double-headed studs (Type 2) mechanically crimped into a non-structural steel shape or attached to a steel plate by spot welding or tack welding. These stud assemblies are not intended for use as shear connectors in steel-concrete composite construction.
Note 1: The configuration of the studs for stud assemblies is much different than the configuration of the headed-type studs prescribed in Clause 9, Figure 9.1 of AWS D1.1/D1.1M. Ratios of the cross-sectional areas of the head-to-shank of the AWS D1.1/D1.1M studs range from about 2.5 to 4. In contrast, this specification requires the area of the head of the studs for stud assemblies to be at least 10 times the area of the shank. Thus, the standard headed-type studs in Clause 9, Figure 9.1 of AWS D1.1/D1.1M do not conform to the requirements of this specification for use as stud assemblies for shear reinforcement.  
1.2 This specification is applicable for orders in either inch-pound units or in SI units.  
1.3 The values stated either in inch-pound or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. 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 this specification.  
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.
