The concrete is generally graded along with its characteristic compressive strength value. For example, concrete of grade M15, concrete of grade M20, concrete of grade M 25 etc.

Density of all Grades of Concrete. Density of M20,M25 and M30 is to be taken as 25kn/m³. Similarly for higher grade of concrete and for high strength of concrete up to M60 grade of concrete the density will be 27.5 kn/m³. For Ultra high strength concrete like M80 & M100 the density of concrete will be in the range of 29 kn/m³.

Concrete with a PSI rating of 6000 or more is considered high-strength concrete. It is typically found in nuclear power plants and other areas where radiation contamination is possible. High strength concrete has a lower water-cement ratio, giving it additional durability and strength. Free Quotes from Concrete Contractors.
