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.
