**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 3

**Apparatus required :**

Le-Chatelier flask Weighing balance of 0.1 Gram accuracy

**Sample materials required :**

Cement Kerosene

**Important key points :**

The specific gravity of kerosene is 0.79 gram per centimetre cube The specific gravity of water is 1 gram per centimetre cube

**Interesting point : **The reason behind kerosene is used to find out the specific gravity of cement and not the water is given below;

In general, to calculate the specific gravity of the material, we use water. In the case of cement, we use kerosene for finding specific gravity of it. Cement hydrates and forms calcium oxide when it reacts with water Cement won't show any type of reaction when it mixed with kerosene. Hence kerosene is used to find the specific gravity of cement instead of water.

I hope you learn some new concepts from my answer. Thank you.
