Q: The cement becomes useless if its absorbed moisture content exceeds
  • A. 0.01
  • B. 0.02
  • C. 0.03
  • D. 0.05
Correct Answer: Option D - • Absorption of 1% to 2% of moisture has no appreciable effect on quality of cement. • The cement becomes useless if it absorbed moisture content more than 5%. • Hence when cement is to be stored for a long period, it should be stored in air-tight chamber.
