What is the cement content for 1m3 of
M20,M25 concrete?
Answer
M25
Cement =320 kg/cu.m
fine aggregate= 751 kg/cu.m
coarse aggregate =
20 mm = 977 kg/cu.m
10 mm =380 kg/cu.m
w/c ratio = 0.43
quantity of water= 138 liter
M20
Cement =290kg/cu.m
fine aggregate= 696 kg/cu.m
coarse aggregate =
20 mm = 1029 kg/cu.m
10 mm =400 kg/cu.m
w/c ratio = 0.5
quantity of water = 145 liter
