ASTM C1314-21 PDF Download

ASTM C1314-21 is a standard test method that provides guidelines for determining the compressive strength of masonry prisms. The purpose of this test method is to verify that the masonry materials used in construction meet the specified compressive strength requirements.

This test method also serves as a means of evaluating the compressive strength characteristics of in-place masonry construction. It involves testing prisms obtained from the construction site, following the guidelines outlined in Practice C1532/C1532M for sampling. It is important to note that decisions relating to the preparation of field-removed prisms for testing, determining the net area, and interpreting the compression test results require professional judgment.

Additionally, this test method provides guidance for conducting research on the effects of various prism construction or test parameters on the compressive strength of masonry. Any deviations from the standard test method should be clearly reported in such research studies. However, it is emphasized that research prisms should not be used to verify compliance with specified compressive strength requirements of masonry.

The testing laboratory performing this test method should also be evaluated in accordance with Practice C1093. Appendix X2 of the standard includes additional information and guidance for researchers on aspects of materials, construction, and analysis.
