Coarse Aggregates in Construction Types and Uses
WebMar 1, 2009 · The current method of specific gravity and absorption of coarse aggregate testing is based on the AASHTO T 85 and ASTM C-127 standards. This approach involves the soaking of the coarse aggregate samples for 15h (AASHTO T 85) and 24 . ± 4 h (ASTM C-127), and drying the aggregate to its saturated-surface dry (SSD) state with the aid of a … WebAASHTO M 132 and ASTM E 12 define specific gravity as: “…the ratio of the mass of a unit volume of a material at a stated temperature to the mass of the same volume of gas-free … selc asheville office
Specific gravity and absorption of fine aggregate lab report …
WebSpecific gravity (S.G.) is a measure of the relative density of a substance as compared to the density of water at a standard temperature. Physicists use 39.2 F (4 C) as the standard, but engineers ordinarily use 60 F. In the International System of Units (SI Units), the density of water is 1.00 g/cm 3 at the standard temperature. Web1) Bulk Specific Gravity is used to determine the volume occupied by the aggregates in the different mixtures. 2) It is used to compute the voids in the aggregates. 3) Bulk specific gravity (SSD) is used if the aggregate is wet. 4) Bulk specific gravity (OD) is used for computations when the aggregate is dry.
