(Test Method)Standard Test Methods for Sampling and Testing Concrete Masonry Units and Related Units
Standard Test Methods for Sampling and Testing Concrete Masonry Units and Related Units
SIGNIFICANCE AND USE
These test methods provide general testing requirements for application to a broad range of concrete products. Those general testing requirements are included in the body of this standard.
Note 2—Consult manufacturer, supplier, product specifications, or other resources for more specific measurement or testing guidelines for those products not addressed with the annex of this standard.
These test methods provide specific testing requirements in two distinct sections, the requirements applicable to all units covered by these test methods and those applicable to the specific unit types. The requirements applicable to all units are included in the body of these test methods and those applicable to the specific unit types are included within the annexes.
SCOPE
1.1 These test methods provide various testing procedures commonly used for evaluating characteristics of concrete masonry units and related concrete units. Methods are provided for sampling, measurement of dimensions, compressive strength, absorption, unit weight (density), moisture content, flexural load, and ballast weight. Not all methods are applicable to all unit types, however.
1.2 Specific testing and reporting procedures are included in annexes to these test methods for the following specific unit types: Annex A1—Concrete masonry units (Specifications C 90, C 129) Annex A2—Concrete brick (Specifications C 55, C 1634) Annex A3—Segmental retaining wall units (Specification C 1372) Annex A4—Concrete interlocking paving units (Specification C 936) Annex A5—Concrete grid paving units (Specification C 1319) Annex A6—Concrete roof pavers (Specification C 1491)
1.3 The test procedures included in these test methods are also applicable to other types of units not referenced in these test methods, but specific testing and reporting requirements for those units are not included.
1.4 These test methods include the following sections: Section Scope1 Referenced Documents2 Terminology3 Significance and Use4 Sampling5 Measurement of Dimensions6 Compressive Strength7 Absorption8 Calculations9 Report10 Keywords11 Annexes—Test Procedures Concrete Masonry UnitsAnnex A1 Concrete BrickAnnex A2 Segmental Retaining Wall UnitsAnnex A3 Concrete Interlocking Paving UnitsAnnex A4 Concrete Grid Paving UnitsAnnex A5 Concrete Roof PaversAnnex A6 Determining Plate Thickness Requirements for Compression TestingAnnex A7 Worksheet and Test Report for Concrete Masonry UnitsAppendix X1
Note 1—The testing laboratory performing these test methods should be evaluated in accordance with Practice C 1093.
1.5 The values stated in inch-pound 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 and health practices and determine the applicability of regulatory limitations prior to use.
