This test method covers compression tests of masonry prisms for determining comparative data on the compressive strength of masonry built in the laboratory with either different masonry units or mortar types, or both.
NOTE 1—This test method is not intended for use in establishing the compressive strength of a particular set of materials by a preconstruction evaluation or to evaluate quality of materials and workmanship during construction. Nor is this test method intended for use in determining the compressive strength of masonry built at the job site with the same material and workmanship to be used, or being used, in a particular structure (see Test Method C 1314).
Test specimens are short compression prisms: the influence of slenderness ratio is taken into account either by proportions of the fabricated specimens or by the application of a correction factor.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
