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.

A slump test is a method used to determine the consistency of concrete. The consistency, or stiffness, indicates how much water has been used in the mix. The stiffness of the concrete mix should be matched to the requirements for the finished product quality. Slump is a measurement of concrete's workability, or fluidity. It's an indirect measurement of concrete
