Materials Free Full-Text Lightweight Concrete Produced ...

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. This paper proposes a two-stage casting process to produce a lightweight concrete.

STUDY OF LIGHTWEIGHT CONCRETE BEHAVIOUR

Lightweight concrete can be defined as a type of concrete which includes an expanding agent in that it increases the volume of the mixture while giving additional qualities such as nailbility and lessened the dead weight. Lightweight concrete maintains its large voids and not forming laitance layers or cement films when placed on the wall.
