A concrete mix with a 3 inch slump, w/c (water content) ratio of 0.50, and sand with a fineness modulus of 2.4 contrains 1700 lb/cubic yard of coarse aggregate. Compute the required weight of the coarse aggregate per cubic yard. To adjust the mix so as to increase the compressive strength, the w/c ratio is reduced to 0.45. Will the quantity of coarse aggregate increase, decrease, or stay the same?
