Students in the materials lab performed the specific gravity test and bulk unit weight and voids of aggregate on a sample of coarse aggregate and obtained the following data: Mass of oven dried aggregate: 1042 g Mass of aggregate submerged in water: 646 g Mass of saturated surface dry aggregate: 1058 g Bulk dry specific gravity of aggregate. Find the absorption of aggregate. If the dry rodded unit weight of aggregate found to be 1695 kg/m3 , calculate the percent voids between aggregate particles in this test. We blend this aggregate with other aggregate with bulk dry specific gravities of 2.23. Calculate the bulk dry specific gravity of the blend if the blend proportion is 40:60.
