## Calculate Quantities of Materials for Concrete -Cement ...

Thus, for the proportion of mix considered, with one bag of cement of 50 kg, 0.1345 m 3 of concrete can be produced.. We have considered an entrained air of 2%. Thus the actual volume of concrete for 1 cubic meter of compacted concrete construction will be = 1 -0.02 = 0.98 m 3.. Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement.
