How To Calculate Weight of Cement required for 1 cubic meter of M20 Grade concrete

 

 The bulk density of frequently used cement varieties (both PPC and OPC) is 1440 kg/cu.m.

Weight of cement needed          = volume of cement x bulk density of cement 

                                                   = 0.285 cu.m x 1440 kg/cu.m  

Weight of cement needed          = 410 kg

No of cement bags required      = 410/50

                                                  = 8.2 bags
