A normal weight concrete weighs 2400 kg per cubic meter or 145 lbs per cubic foot 3915 lbs per cubic yard. The unit weight of concrete density varies depending on the amount and density of the aggregate, the amount of entrained air and entrapped air, and the water and cement content.
The density of M25 standard concrete is 2398 kgm 3 and has a compressive strength of 25 Nmm 2.It finds use in common applications like residential... See full answer below.
The variable density is normally described in kg per m 3, where regular concrete is 2400 kgm 3. Variable density can be as low as 300 kgm 3 , 17 although at this density it would have no structural integrity at all and would function as a filler or insulation use only.
Apr 08, 2018018332As grades of concrete vary between 15 to 80 Nmm 2. These grades differ on the basis of mix proportions.

Strength and Durability are affected by the density of the concrete. Denser concrete is more watertight or less permeable. Concrete durability INCREASES with strength. Well made concrete is very important to protect the steel in reinforced concrete. See CHAPTER 17 Reinforced Concrete Strength of concrete in the hardened state is usually
