How many bags of cement will be used in concrete mix design of 1:1.5:3 ?

For 1 Cum concrete:-

Note: 1 cum concrete(wet) =1.54 cum concret(dry content)

=1.54/(1+1.5+3)=.28 cum cement

=.28/.0347=8.07 Bags of cement (50 Kg capacity).

Now for Sand:-

=.28*1.5=.42 Cum sand

For Aggregates:-

=.28*3=.84 Cum aggregates

IT DEPENDS ON NUMBER OF POLLS REQUIRED WHICH DEPENDS ON SPACING BETWEEN TWO ADJASCENT POLLS, AND DIAMENSION OF POLLS.

The answer is 1 bag of cement
