Civil Engineering Basics - What is Cement & its types ?

 

Cement

Cement is a material that has cohesive and adhesive properties in the presence of water. Such cements are called hydraulic cements. These consist primarily of silicates and aluminates of lime obtained from limestone and clay.

Types of Cement

There are different types of cement as classified by the Bureau of Indian Standards (BIS)

1. 33 grade ordinary portland cement

2. 43 grade ordinary portland cement

3. 53 grade ordinary portland cement

4. Portland Cements

(a) Ordinary portland cement

(b) Rapid hardening cement

(C) Extra rapid hardening cement

(d) Low Heat port land cement

(e) Portland Blast furnace slag cement

(f) Portland Pozzolana cement

(g) Sulphate resisting portland cement

(h) white port land cement

(i) Coloured portland cement

5. High Alumina Cement

6. Super Sulphate Cement

7. Spacial Cements

(a) Masonry Cement

(b) Trief Cement

(c) Expansive Cement

(d) Oil well Cement
