Generally its easy to find it.

Find Total Parts = (1+2+4)=7 Parts.

For 1 cu.m of concrete the total parts = 1.57

Unit weight of cement = 1440 kgs

Cement = (1440/7)*1.57 = 322.97/50kgs = 6.46bags.

1 bag cement= 1.25cft

Sand = 6.46*1.25 = 8.075 cft*2 =16.15 cft

Aggregate = 8.075 cft*4 =32.3 cft.

Thats all...

Cement = 6.46 bags
Sand = 16.15 cft
Aggregate = 32.3 cft.
