in India, for m-20 cement concrete, for 1 cu.m.- 3.47 quntl cement-0.45 cu.m. sand( fine aggr.)- and 0.90 cu.m. chips( course aggr.), that means 6.94 or 7 of 50 kgs.cement bags
so for M-25, for 1 cu.m. 4.03 qntls cement- 0.45 sand- 0.90 cu.m. chips, so 8.06 cement bags
M20 - 6.20bags
1 bag
Yes. OPC 43 grade cement can be used to make M20 grade concrete.It can be used to make concrete up to M30 Grade.See related link.
260 kg/cu m
Usually for a design mix as per Indian Standards when the mix proportions are arrived for M25,the total cement consumption will be around 400 kg.From that the number of cement bags will be 8 numbers for 1 cum
M20 - 6.20bags
concrete and cement
For M10 (1:3:6) Grade of concrete cement bag consumed = 4.4 bags/cum M15(1:2:4) Grade of concrete cement bag consumed = 6.6 bag/cum M20(1:1.5:3) Grade of concrete cement bag consumed = 8.2 bag/cum
1 bag
For M20 grade concrete, the mix proportion is 1:1.5:3 (cement:sand:coarse aggregates). If we consider a volume of 1 cubic meter, approximately 320 kg of cement would be needed.

It depends on the Grade of Concrete. general grades are M15, M20, M25 etc. here are the nos. of bag required -------------------Bag for 1 cum---------------Bag for 5 cum M15------------------- 6.4----------------------------32 M20-------------------- 8-----------------------------40 M25--------------------12----------------------------60
Usually for a design mix as per Indian Standards when the mix proportions are arrived for M25,the total cement consumption will be around 400 kg.From that the number of cement bags will be 8 numbers for 1 cum
