How to calculate cement, sand and coarse .
Cement Volume – m 3 or Bags Sand Volume – m 3. Coarse Aggregate – m 3. Water Cement Ratio Calculation. From the IS Code standard, Assuming the watercement ratio for M20 is Therefore required water quantity = Cement Volume X WC Ratio = X = m 3 Unit weight of water = 1000 Litres / m 3
