Compute required weight of coarse aggregate per cubic yard

Reference no: EM13297439

A concrete mix witha 3-inch slump, w/c rtion of .5, ans 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. abjust the mix so as to increase the compressive strenght, the water-to-cement ratoon is reduced to .45. Will the quantity of coarse aggregate increase, decrease or stay the same?
