The ingredient weights for making 1 yd3 (cyd) of concrete by assuming aggregates in SSD state are given below. Coarse Aggregates: 1,575 lb; Fine Aggregates: 1,100 lb; Cement: 700 lb; Water: 315 lb

After performing a trial batch, it is determined that we need to increase the mix water content from 315 lb to 328.5 lb to correct the slump. For the same ingredients, recalculate the weight of cement to achieve a concrete with the same compressive strength as the original concrete mix design.
