Compute the required weight of the aggregate per cubic yard

Reference no: EM13323510

Concrete mix with a 3 in slump, w/c ratio of .5, and sand with a fineness modulus of 2.4 contains 1700 lb of coarse aggregate.
1. compute the required weight of the aggregate per cubic yard.
2. the w/c ratio is reduced to .45. will the quantity of coarse aggregate increase, decrease, or stay the same?
