Setting and hardening of the cement

It knows that setting is transformation of plastic cement to solid cement.

It is exothermic cement that means detaches high quantity of hot.

Hardening is a progressive and slow acquisition of resistance over time.

The cement when it is settled it composed essentually of tobermorite with other minor compounds.

The Tobermorite is the compound which gives durability, hardness and resistance.

There are different variables which change characteristics of settled cement:

• Temperature of kneading water.

          Own temperature of cement or Temperature of kneading water affects the settiling of cement.If            there is Hot water it will settle quickly.

• Enviromental temperature 

          If there is cold, it will settle slowly.

• Grinding cement fineness

          If cement contains fine particles, it will settle quickly.

So this is all stuff that involves in the process of settle and hardness.
