C Specification for Admixtures for Masonry Mortars. Table 3 details the recipes required for each mortar type specified by proportion.
Type M mortar has the highest strength. Portland cement-lime mortars are specified in two steps. ASTM Standard C provides both a proportion specification and a property specification for each mortar type. Foundation wall, retaining wall, manholes, sewers, pavements, walks, and patios.
This abstract is a brief summary of the referenced standard. Type K mortar has the lowest compressive strength. Work Item s – proposed revisions of this standard. Mortar for such masonry should be selected with due caution. 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.
Historical Version s – view previous versions of standard. When neither proportion nor property specifications are specified, the proportion specifications shall govern, unless data are presented to and accepted by the specifier to show that mortar meets the requirements of the property specifications.
Four types of mortar are covered in each of two alternative specifications: C Specification for Admixtures for Masonry Mortars.
