The basic approach used in the ACI mixture proportioning method

Q. What is the basic approach used in the ACI mixture proportioning method?


A. Mixture proportioning is done on a volumetric basis. The w/cm is selected on the basis of the required strength or exposure conditions. The volume of water is based on the required slump and aggregate size. The amount of coarse aggregate is based on its maximum size and the overall fineness of the fine aggregate (ACI PRC-211.1R).
