If you Consider M25 Grade Concrete Nominal mix Design is
1:1:2(1 Cement:1 Sand:2 Aggregates)

1+1+2=5

Volume of Dry Mix=1.5% X Volume of wet mix
If you Consider 1 Cum Concrete
Cement=1/5X1.5(1)=0.3 Cum(1 Bag of Cement=50 Kgs=1.235
Cft=0.035 Cum)
Then 0.3 /0.035=8.57 bags=428 kgs

Sand=1/5X1.5(1)=0.3 Cum=10.584 Cft

Aggregates=2/5X1.5(1)=06 Cum=21.168 Cft
