Properties of concrete - Wikipedia

Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft).

High Performance Concrete Topic

High-performance concrete (HPC) is concrete that has been designed to be more durable and, if necessary, stronger than conventional concrete. HPC mixtures are composed of essentially the same materials as conventional concrete mixtures, but the proportions are designed, or engineered, to provide the strength and durability needed for the structural and environmental requirements of the project.

Difference Between Lightweight & Heavyweight Concrete

The key difference between lightweight and heavyweight concrete is the density of the aggregate. Lightweight concrete is made using aggregate whose density is less than 2,100 kilograms per cubic yard (or 131 pounds per per cubic foot), while aggregates with greater densities give rise to so-called heavyweight concrete.
