Mix Design Of Cement Concrete C

The mix ratios for C20, C25, C30, C35, and C40 concrete

The mix ratios for concrete are typically expressed in terms of the proportions of cement, sand, and coarse aggregates. In the case of C20 concrete, the "C" stands for compressive strength, and "20" denotes a characteristic compressive strength of 20 megapascals (MPa) or 20 N/mm2.
