With storage, the strength of cement:

Detailed Solution for APSC AE CE Paper 1 Mock Test - 9 - Question 29
  • Due to the hygroscopic nature of cement, it quickly absorbs moisture from the atmosphere.

  • This moisture or dampness is the main hazard for cement, making it hard like stone, and it converts it to a useless material not suitable for construction.

  • Storage of cement requires more care as the strength of cement decreases with time.

  • Storage of cement should be done so that it is not exposed to the atmosphere, which can be done by packing in air-tight bags.

  • For storage guidelines, rules are mentioned in IS 4082:1996
