Mortar Compressive Strength - Civil Engineering …

Mortar compressive strength is influenced by mortar water content at the time of set. Because molded mortar specimens are not in contact with absorptive masonry units and are not subjected to other mechanisms of water loss, they have a higher water content than mortar in the masonry. Higher water content results in lower compressive strength.

Cement Mortar | Estimation of Cement, Sand & Water in ...
