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.

concrete strength of M20 Grade by partial replacement of cement from 0% to 2.0% with artificial fiber (polypropylene fiber) and from 0% to 2.5% natural fiber (coconut fiber). The mix design of M20 grade concrete was designed as per the method specified in IS 10262-1982.

Concrete grade is denoted by M10, M20, M30 and so on according to their compressive strength. Read More: Concrete Mix Design Step By Step Full Calculation. Concrete Grade As Per Indian Standards: The "M" refers Mix and Number after M (M10, M20) Indicates the compressive strength of concrete after 28 days of curing and testing.

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.

To evaluate the split tensile strength of control concrete of M20 grade and rice husk ash concrete produced by replacing cement by raw RHA in different percentage (0%, 5%, 10%, 15%.) To determine the optimum dosage of the rice husk ash to be added to the concrete mix.
