The Cement Becomes Useless if its Absorbed Moisture Content Exceeds

Answer: D. 0.05

The cement becomes useless if its absorbed moisture content exceeds 0.05.

Solution

The cement becomes useless if its absorbed moisture content exceeds 0.05. When water comes in contact with cement, it forms a bond with cement molecules. The reaction is exothermic and is called heat of hydration.

After this, cement does not remain in the proper dry state and binding property of cement is lost.
