ASTM C1314-10

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Compressive Strength of Masonry Prisms
This standard is issued under the fixed designation C1314; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This test method covers procedures for masonry prism construction and testing, and procedures for determining the

this test method is used for research purposes, the construction and test procedures within serve as a guideline and provide control
parameters.
1.2 This test method also covers procedures for determining the compressive strength of prisms obtained from field-removed
masonry specimens.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered 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 and health practices and determine the applicability of regulatory
limitations prior to use.

4. Significance and Use
4.1 This test method provides a means of verifying that masonry materials used in construction result in masonry that meets
the specified compressive strength.
4.2 This test method provides a means of evaluating compressive strength characteristics of in-place masonry construction
through testing of prisms obtained from that construction when sampled in accordance with Practice C1532. Decisions made in
preparing such field-removed prisms for testing, determining the net area, and interpreting the results of compression tests require
professional judgmen
