Properties of high-performance LWAC for precast

2003-1-1  Lightweight aggregate concrete (LWAC) has been used successfully for structural purposes for many years. For structural applications of lightweight concrete, the density is often more important than the strength. A decreased density for the same strength level reduces the self-weight, foundation size and construction costs.

Applications of Structural Lightweight Concrete Concrete ...

Occasionally the word "problem" is associated with structural lightweight concrete. As a general rule, the so-called problems encountered in structural lightweight concrete are not inherent in the aggregate, per se, but rather are created by non-adherence to fundamental knowledge of the properties of both the aggregate and the concrete.

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.
