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.
