Q: If water required for 1 bag of cement is 30 L, the water-cement ratio is
  • A. 0.40
  • B. 0.50
  • C. 0.60
  • D. None of the above
Correct Answer: Option C - If 30 litre water is required for 1 bag of cement, then water cement ratio will be 0.60. Water cement ratio is generally expressed in volume of water required per 50 Kg. In general, if the water to cement ratio of concrete increases, its permeability Increases.
C. If 30 litre water is required for 1 bag of cement, then water cement ratio will be 0.60. Water cement ratio is generally expressed in volume of water required per 50 Kg. In general, if the water to cement ratio of concrete increases, its permeability Increases.
