(Test Method)Standard Test Method for Examination and Analysis of Hardened Masonry Mortar
Standard Test Method for Examination and Analysis of Hardened Masonry Mortar
SIGNIFICANCE AND USE
This test method provides procedures for petrographic examination and chemical analysis of mortar for components of masonry mortar. These components may include portland cement, hydrated calcitic or dolomitic lime, masonry cement, aggregates, and air.
The test method consists of procedures and sub-procedures, each requiring a substantial degree of petrographic and chemical skills and relatively elaborate instrumentation.
The chemical data considered together with results of petrographic examination of a mortar provide for calculation of component proportions and thus allow a determination of mortar composition as represented by Types M, N, S, and O in Table 1 (Proportion Specification Requirements) of Specification C 270.
Failure of a mortar to have the composition of any type as defined in Table 1 of Specification C 270 does not necessarily mean that the mortar does not meet the requirements of Specification C 270. The mortar may meet the alternative requirements of Table 2 (Property Specification Requirements) of Specification C 270.
The maleic acid method of analysis is not applicable for the analysis of mortar because it is greatly influenced by carbonation and does not provide for the determination of calcium.
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—This method is also applicable to hydraulic cement-based stucco and plaster. 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:SectionSampling7Petrographic examination8Chemical analysis9Mortar proportion calculations10Report11
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.
