24.10.2018· The concrete grades are normally indicated as M30 or C30 or C30/37 and so on depending on the code. The alphabet ‘M’ or ‘c” refers to it as a ‘Concrete Mix’ and the number that follows indicates the characteristic strength of that that mix in MPa at 28 days.Grade Of Concrete - Their Ratio, Uses & Suitability,01.10.2019· As per BS 8500-2 British/European standards The grade of concrete is denoted as C10, C15, C20, C25, etc., ‘C’ which means ‘ Concrete Strength class’ and number behind C refers to characteristic Compressive strength of Concrete in N/mm2 @ 28 days when tested with the 15 cm dia. & 30 cm height cylinder in a direct compression test.Concrete Grades | Different Types & Specification,,22.08.2020· Concrete grades defines as a minimums strength of the concrete it must possess after the 28th days of constructions with properly control quality. The real category denoted with the prefix of ‘‘M’’ basically desired MPa strengths. Like example, grade concrete is the strength of 20 MPa, so we indicated 20 by the M20. The meaning of M is using for Mixing, so we called 20 power in short M20.

3- Standard grade of concrete. 4- High strength concrete grades. 1- Lean concrete. Lean concrete is a mix where the amount of cement is lower than the amount of liquid present in the strata.
