Aggregate: Mechanical Properties of Aggregate | Concrete
Usually the specific gravity of most aggregates varies between 26 and 28 Specific gravity of certain materials as per concrete hand book CA1 Bombay may be assumed as shown in Table 49 Method of Determination of Specific Gravity of Aggregate: IS2386PartIII1963 describes various procedures to find out the specific gravity of aggregatesAs per the definition given in the ‘IS: 2386 (Part III) – 1963’, (Indian Standard Methods of Test for Aggregates for Concrete – Specific Gravity, Density, Voids, Absorption and Bulking), the specific gravity of coarse aggregates is the weight of the aggregates dried to constant weight in an oven at 100°C divided by its absolute volume including the natural voids within the aggregateSpecific Gravity of Coarse Aggregates: Its Importance
