Reference no: EM13320131

A concrete mix with a 3in slump, w/c ratio of .5, and sand with a fineness modulus of 2.4 contains 1700lb/yd3 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 .45. Will the quantity of coarse aggregate incease, decrease, or stay the same?
