A concrete mix with a 3-inch slump, w/c ratio of 0.50, and sand with a fineness modulus of 2.4 contains 1700 lb/yd^3 of coarse aggregate. Compute the required weight of coarse aggregate per cubic yard. To adjust the mix for increased comkpressive strength, the water to cement ratio is reduced to 0.45. Will the quantty of coarse aggregate increase, decrease, or stay the same? Explain the answer.
