There is no ASTM standard method for measuring the composition or physical properties of hardened mortars removed from a structure.

A. True
B. False

Answer :

Final answer:

The claim that no ASTM standard method exists for measuring the composition or physical properties of hardened mortars is false; ASTM provides methods like ASTM C1324 for such analysis.

Explanation:

False: There is no ASTM standard procedure for determining the physical or compositional characteristics of hardened mortars that have been removed from buildings. ASTM International has developed standards for testing hardened concrete and mortar, including ASTM C1324 which outlines a test method for examining the petrographic characteristics of hardened masonry mortar. While this test does not give a quantitative analysis of composition, it provides valuable qualitative information. Moreover, physical properties of mortar can be assessed using other standards like ASTM C140/C140M.
