Masonry mortar holds masonry units together, and also holds them apart (compensates for their dimensional tolerances). Mortar for unit masonry is addressed by ASTM C270, which in turn cites other ASTM specifications. Specifying masonry mortar under ASTM C270 requires three choices: • The designer must choose a cementitious system. Three options are possible: cement-lime mortar, masonry-cement mortar, or mortar-cement mortar.
