Mar 13, 2019· Specific Gravity. The ratio of weight of oven dried aggregates maintained for 24 hours at a temperature of 100 to 1100C, to the weight of equal volume of water displaced by saturated dry surface aggregate is known as specific gravity of aggregates. Specific gravities are primarily of two types. Apparent specific gravity; Bulk specific gravity
The specific gravity of a solid is the ratio of its mass to that of an equal volume of distilled water at a specified temperature. Because the aggregates may contain water-permeable voids, so two measures of specific gravity of aggregates are used: apparent specific gravity and bulk specific gravity.
(a) Crushing test for stones: The crushing strength of a stone greatly depends upon its texture and specific gravity.
