Required tests:
Water RetentionMortarASTM C1506Water Retention of Hydraulic-Cement Based Mortars and Plasters
Air ContentMortarASTM C185

Air Content of Hydraulic Cement Mortar

Mortar is cast to the desired consistency, and it is consolidated in a 400mL brass measuring container described in ASTM C185. The weight/volume is determined, and the air content is calculated based on the mix proportions.

Compressive StrengthMortarASTM C109

Compressive Strength of Hydraulic Cement Mortars Using 2″ Cube Specimens

Cube specimens are cast and three are tested at each of 1, 3, 7, and 28 days of curing. Samples are cured for the first 24 hours in a standard moist room, and all subsequent days in saturated lime water.
