Unit weight of fine aggregate was also determined in accordance with ASTM C29 [], whereas water absorption and specific gravity of fine aggregate were found in accordance with ASTM C128 []. From these testing procedures, fineness modulus, unit weight, water absorption, and specific gravity of fine aggregate were found as 2. kg/m 3, %, and, respectively.

Overview The fine aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a fine aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the coarse aggregate specific gravity test.
