we use M30 grade concrete commercial slabs like shopping malls . college buildings
proportion of M30 Grade of concreete is 1 :.5 :1 .
Density of M30 and any fresh concrete is 2400kg/cu.m and reinforced concrete density you can take 2500 kg/cu.m
cost of RCC m thirty per meter cube
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
around 22.. the basic rule is around 70% of target mean strength..
