### Specific Gravity of Cement - Details & Test Procedure ...

Mainly “Specific Gravity” is the is the ratio of the density of a substance to the density of a reference substance at a fixed temperature. On the other words, it is the ratio of the mass of a substance to the mass of a reference substance. And the theme is also same for cement. Specific Gravity of cement is the ratio of the density or mass of cement to the density or mass of a reference ...

### Specific Gravity of Cement - Detailed Explanation – Civilology

If the specific gravity of cement is greater than 3.19 then, the cement is either not minced finely as per the industry standard or it has more moisture content which will affect the mix and bonding. This is why you find lots of chunks while mixing old stock cement for concrete.

### Specific Gravity Of Cement Test - How To Calculate ...

Specific Gravity Of Cement Test: Specific gravity can be defined as the density of any substance to the density of other reference substance at a specified temperature. For example, to determine the specific gravity of cement will consider water as reference substance.

### Specific gravity - Wikipedia

Specific gravity, also called relative density, is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. 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.
