Concrete Mix Ratio

Concrete Mix Formula. Example: M 15 mixing concrete ratio of Concrete (1:2:4) here (1 no of Cement quantity, 2 nos of Send quantity, 4 nos of Aggregate quantity, Here quantity measured by mixing box) it also called recipes for concrete. E.g., M15(1:2:4), the quantity of cement, sand (fine aggregate), and coarse aggregate are batched in volume as per the fixed ratio 1:2:4. Get price
