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.

How to Make Lightweight Concrete Blocks? - Block Making ...

Add Sand. The material that the most make heavier concrete mixture is sand. Since we want to produce lightweight concrete blocks, we will use as little sand as possible. We recommend 22 liters of sand for the lightest mixture. You can add one more bucket of sand to get stronger blocks. The heavier your products, more durable they are.

Lightweight Concrete - What Is Lightweight Concrete And ...

The light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less. The lightweight aggregates used are usually expanded shale, clay, or slate materials that have been fired in a rotary kiln to give them a porous structure, similar to volcanic rock.
