Concrete Mix Ratio Calculatorm20 Concrete Ratio For 1 Cubic Meter

weight of 1 cubic meter of m10, m15, m20 and m25 concrete,weight of 1 cubic meter of m20 concrete. we have to prepare 1m3 of m20 concrete, this is wet volume, to calculate dry volume we will multiply 1.54 in wet volume, so total volume of concrete = 1.54m3, in m20 concrete nominal mix ratio of cement, sand and aggregate is 1: 1.5: 3.calculation of materials for different mix ratio of concrete,today we will discuss how to calculate quantities of materials for different mix ratio of concrete. (dry mix method) we will calculate quantities of materials for 1 m3 concrete (by volume). let us assume the mix proportion is 1 : 2: 4 (cement:sand:stone =a:b:c) volume of wet concrete = 1 m3. volume of dry concrete = 1 × 1.54 = 1.54 m3..
