Cement sand and aggregate ratio for M20 grade concrete is 1:1.5:3. Cement = 1 Part. Sand = 1.5 Part. Aggregate = 3 Part. Total Parts = 1 + 1.5 + 3 = 5.5. Total Material …
Water – Cement Ratio Method of Proportioning Concrete. Thumb Rules for deciding the quantity of water in concrete: (i) Weight of water = 28% of the weight of cement + 4% of the weight of total aggregate (ii) Weight of water = 30% of the weight of cement + 5% of the weight of total aggregate.
