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.

Understanding the Density of Concrete • Aggregate Research ...

The density of concrete is a measurement of concrete’s solidity. The process of mixing concrete can be modified to form a higher or lower density of concrete end product. A very high density of concrete is that made around steel cables that have been stretched by hydraulic jacks. The concrete is allowed to harden and then the jacks are released.
