Answer Posted / syed zafar
M20 means
The mix ratio will be = 1:2:4
That is Cement : Sand : Aggregate
To find out the weight
Add there all = 1+2+4 = 7
1.54 is the design constant
Then for cement (1/7)*1.54 = 0.22m3
One bag (50KG) of cement = 0.0332 m3
Therefore cement required in kg = 332 KG/m3
For sand = (2/7)*1.54 = .44
i.e. = 2*332 = 663 Kgs /m3
For Aggregate = (4/7)*1.54 = .88
i.e. = 2*663 = 1326 Kgs /m3
water cement ratio = 0.42*332 = 140 Kgs
Therefore the weight of one cubic meter of -
Concrete for M20 mix (1:2:4) = 2461 kgs
After exact & all calculations it will come = 2500 kg/m3
