Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance. The reference substance is nearly always water at its densest (4°C) for liquids; for gases it is air at room temperature (21°C).
The determination of the specific surface area serves primarily to check the consistency of the grinding process of one and the same plant. This method only enables a limited assessment to be made of the properties of the cement in use. NOTE: The air permeability method may not give significant results for cements containing ultrafine materials.

Specific gravity of cement is one of the factor, which is used in determination of the density of the cement. Moreover, density of the cement and other materials is one of the vital parameter, which determines the design of the concrete. This is why the specific gravity test of cement is so important.
May 25, 2020· Generally, the specific gravity of cement ranges from 3.1 to 3.16 g/cc. From this we can say that the specific gravity of cement is more than the specific gravity of water that is 1. It means cement will sink in water if we put on the water. Also, we can say that cement is heavier than water.
