Will the quantity of coarse aggregate increase or decrease

Reference no: EM13313287

A concrete mix with a 3 inch slump, w/c ratio of 0.50, and sand with a fineness modulus of 2.4 contains 1.700 lb/yd^3 of coarse aggregate. Compute the required weight of coarse aggregate per cubic yard. to adjust the mix so as to increase the compressive strength, the water-to-cement ratio is reduced to 0.45. will the quantity of coarse aggregate increase, decrease, or stat the same?
