C Specification for Admixtures for Masonry Mortars. Since jobsite water additions may not be the same as those in the laboratory, the properties of field mixed mortar cannot be compared to the property requirements of ASTM C Portland cement-lime mortars are specified in two steps.

These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. As seen in Table 4, compressive strength, water retention and air content tests are required to be performed on the mortar mixed in the laboratory. The compressive strength values resulting from field tested mortars do not represent the compressive strength of mortar tested in the c207 nor that of the mortar in the wall. 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.

These densities are shown in Table 2.
