The type of lightweight aggregate and its volume fraction in a mix determine the density of lightweight concrete. Minimizing the density obviously requires a higher volume fraction, but this usually causes aggregates segregation in a conventional mixing process.

Lightweight concrete with its volume density of about 1800 kg/m 3 shows thermal insulation properties that are similar to those of ceramic brick wall [12,13]. The use of lightweight concrete in prefabricates results in the building's specific weight reduction and thermal and acoustic insulation increase of a building [14,15,16].

Introduction to Lightweight Concrete. Lightweight concrete is a special type of concrete which weighs lighter than conventional or normal concrete. Density of light weight concrete is conventionally low. Generally 300 kg/m³ to 2200 kg/m³ and thus normal concrete has density between 2200 kg/m³ to 2600 kg/m³.
