## The specific gravity of cement:

Definition :The ratio of the weight of a given volume of cement to the weight of an equal volume of water is called specific gravity of cement.

IS Code of specific gravity test is IS 2720 part 3Apparatus required :Sample materials required :Important key points :## Interesting point :

The reason behind kerosene is used to find out the specific gravity of cement and not the water is given below;I hope you learn some new concepts from my answer. Thank you.## AdityaBhandakkar

I added an important formula used to calculate specific gravity of cement.

The specific gravityof cement= ( weight of a given volume of material/weight of an equal volume of water )Or

Specific gravity of cement = ( W2 – W1) / (W2 – W1) – (W3 – W4) x 0.79## Raghvendra_Rai

IS 4031(part 11): 1988specifies the following test procedure to be adopted for the Determination of Specific Gravity of Cement and the test should be done at room temperature.## Apparatus:

## Procedure:

(V1)mark.(V2)mark is then noted after the 24 hour period.It is based on the fact the change in volume observed is equal to the volume of cement and we already know the weight so Density/ Specific Gravity can be calculated and Kerosene is used here because it is a non-polar liquid.

The specific gravity is normally defined as the ratio between the weight of a given volume of material and the weight of an equal volume of water.

The determination of Specific Gravity of Cement as per IS Codes with the use of Standard Le – Chatelier Flask.

The detailed procedure for the determination of specific gravity of cement and its importance is explained in the article below-
