Calculate Quantities of Materials for Concrete -Cement ...

Thus, the quantity of cement required for 1 cubic meter of concrete = 0.98/0.1345 = 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg.

The use of biomass-bottom ash (BBA) to replace natural sand increases the compaction work required to reach a given compactness index mainly because the fineness modulus of the BBA is lower than the natural sand. However, the differential effect of the natural sand and BBA on the compactness of DCC mixtures with time is approximately similar. 5.
