Density of M30 and any fresh concrete is 2400kg/cu.m and reinforced concrete density you can take 2500 kg/cu.m
we use M30 grade concrete commercial slabs like shopping malls . college buildings
proportion of M30 Grade of concreete is 1 :.5 :1 .
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..

Yes. OPC 43 grade cement can be used to make M20 grade concrete.It can be used to make concrete up to M30 Grade.See related link.

The Civil Engineering Data Standards manual states the density of many grades of concrete. Standard density for fresh M-25 concrete is: 2414 Kg/ M3.
