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 respectively and water cement ratio is about 0.55.

The grades of concrete are converted into mix proportions consider for M20 concrete mix proportion will be 1: 1.5: 3 (cement, sand and coarse aggregates). Suitable Concrete Grade For Construction: Based on structural design requirements the grade will be selected and there are two types of concrete mixes, design mix & nominal mix.

Concrete grades are denoted by M10, M20, M30 according to their compressive strength. The "M" denotes Mix design of concrete followed by the compressive strength number in N/mm2. "Mix" is the respective ingredient proportions which are Cement: Sand: Aggregate Or Cement: Fine Aggregate: Coarse Aggregate. we already discussed the mix ...

In this article, we will discuss the what are concrete mix grades use in construction. Further the composition and strength of different concrete mix ratios.. Concrete mix ratio and grades: In concrete mix grades "M" presents concrete mix design ratio and the number after "M" presents MPa or N/mm 2 compressive strength of concrete. For example M10, M15, M20, M25 concrete mix grades.

Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix. These grade of concrete is converted into various mix proportions. For example, for M20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.
