Lightweight concrete

Lightweight concrete can be specified using the notation LC for the strength class, e.g LC30/33, which denotes a lightweight concrete with a cylinder strength of 30MPa and a cube strength of 33MPa. The lighter the concrete, the greater are the differences to be accounted for in the properties of the concrete.

Lightweight Concrete - What Is Lightweight Concrete And ...

A structural light-weight concrete mix has a density of about 105 pounds per cubic foot compared to normal concrete with a density of 150 pounds per cubic foot. The light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less.

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.
