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.
comprehensive strength (mn/m2) Compressive strength otherwise known as "rock crushing strength " takes into consideration properties of mineral constituents of the rock such as hardness, cleavages foliation, degree of magmatisation, banding, void, ratio, shape of voids within rock and nature of banding between the minerals grains.
14. Specific gravity is considered to be a measure of the strength or quality of a material. a) True b) False Answer: a Clarification: Specific gravity is related to the density of the material. If the specific gravity is less, then the material is found to be weaker. A weak material will have lesser quality compared to a stronger material. 15.
