Weighing In on High-Density Concrete - NPCA

Typical concrete density is around 150 lbs/cu ft. Lightweight concrete can weigh as little as 95 lbs/cu ft. High-density concretes range from 190 to 260 lbs/cu ft. Even higher densities (≥ 350 lbs/cu ft) can be attained but are rare. Aggregates: the most critical component The key to high-density concrete is the aggregates.

Density Of Concrete - How Much Does Concrete Weigh?

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.
