Designation: C140/C140M - 21 Standard Test Methods for Sampling and Testing Concrete Masonry Units and RelatedUnits1
1. Scope*
1.1 These test methods provide various testing procedurescommonly used for evaluating characteristics of concretemasonry units and related concrete units. Methods are providedfor sampling, measurement of dimensions,compressivestrength,absorption,unit weight (density), moisture content,flexural load,and ballast weight. Not all methods are appli-cable to all unit types,however.
1.2 Specific testing and reporting procedures are included inannexes to these test methods for the following specific unittypes:
Annex A1—Concrete masonry units
([Specifications Co0,C129j
nnex A2—Concrete and calcium silicate brick(Specifications C55,C73,C1634)
Annex A3-Segmental retaining wall units (Specification C1372)Annex A4—Concrete interlocking paving units
(Specification c36/C936MM)
Annex A5—Concrete grid paving units (Specification C1319)Annex A6Concrete roof pavers
(Specification C1491)
Annex A7——Dey-cast articulating concrete block(Specification D6684)
Annex A8 —-Segmental Concrete Paving Slabs(Specitication C1782/C1782M)
1.3 The test procedures included in these test methods arealso applicable to other types of units not referenced in thesetest methods,but specific testing and reporting requirementsfor those units are not included.
