Bulk Specific Gravity (Gsb)– the ratio of the mass, in air, of a volume of aggregate (including the permeable and impermeable voids in the particles, but not including the voids between particles) to the mass of an equal volume of gas-free distilled water at a stated temperature. save Save SPECIFIC GRAVITY OF CEMENT For Later. 10K views. 1 Up votes, mark as useful. 1 Down votes, mark as not useful. SPECIFIC GRAVITY OF CEMENT. Uploaded by Rohit ... AASHTO T 85 and ASTM C 127: Specific Gravity and Absorption of Coarse Aggregate; Background. Specific gravity is a measure of a material’s density (mass per unit volume) as compared to the density of water at 73.4°F (23°C). Therefore, by definition, water at a temperature of 73.4°F (23°C) has a specific gravity of 1. The apparatus constant is determinate by measuring permeability of reference cement of known specific surface. The procedure repeats three times for three samples of cement bed. For each sample is calculated constant K from formula: where S0 is the specific surface of the reference cement [cm 2.g-1] Gs = Specific Gravity of stone. Note—If the Specific Gravity of the stone is different than 2.5, then the above equation can be used to determine the appropriate size using the actual Specific Gravity. If required, provide bedding stone that, in-place, meets the gradation requirements shown in Table 3 or as otherwise shown on the plans.
