Standard Test Method for Examination and Analysis of Hardened Masonry Mortar

SCOPE
1.1 This test method covers procedures for petrographic examination and chemical analysis of samples of masonry mortars. Based upon such examination and analysis, proportions of components in masonry mortars can be determined.  Note 1-Some historic mortars may contain non-resolvable constituents that may interfere. However, significant information may be obtained by petrographic examinations.
1.2 Interpretations and calculations of chemical results are dependent upon results of the petrographic examination. The use of the chemical results alone is contrary to the requirements of this test method.  
1.3 Procedures for sampling, petrographic examination, chemical analysis, and calculations of component proportions are given in the following sections:  Section Sampling 7 Petrographic examination 8 Chemical analysis 9 Mortar proportion calculations 10 Report 11
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 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.
