12-05-2020· It should be designed through Design Mix procedure alone. Codebook or textbook did not mention in anyplace that volumetric Mix ratio of M25 grade concrete is 1:1:2. In fact, IS456 codebook clearly says that Nominal Mix can be used only for M20 concrete or lower. Nominal Mix concrete may be used for concrete of M20 or lower.
Step-1: Calculate Volume of Materials required. Density of Cement = 1440 kg/cum (Approx) Volume of 1 Kg of Cement = 1/1440 = 0.000694 cum. Volume of 01 bag (50 kg) of cement = 50 X 0.000694 = 0.035 cubic meter (cum) Since we know the ratio of cement to sand (1:2) and cement to aggregate (1:4)
In the case of the wet concrete (WCC), mixing ratios of 1 ∶ 1, 1. ∶ 1.5, and 1 ∶ 1.75, except for strength at curing ages of 14 days and 28 days at a 1 ∶ 2 mixing ratio, showed higher bond strength distribution compared to that of the dried mortar (ADM
