how much tensile strength of M20 grade concrete at 28 Days
concrete and cement
M20 refers to the grade of the concrete generally used in construction purpose. Here, M refers to mix & number 20 refers to the characteristic strength of concrete. the proportions of this grade is (1:1 1/2: 3). Along with this there are some more grades used in constructions i.e., M5, M7.5, M10, M15, M25, M30................. M80

Required slump height of M20 for different concrete structures, are normally calculated by the required slump value, which would come out to be 100 lits.
it is concrete mix which gain strength 20kn/mm2 in 28 day of curing....
