What Is Lightweight Aggregate Concrete And Its Uses?

The lightweight aggregate is a kind of coarse aggregate which is used in the production of lightweight concrete products like concrete block, structural concrete, and pavement.. The shape of the lightweight aggregate used in concrete can be cubical, rounded, angular, or of any other shape.The shape and texture can directly affect its workability. The compressive strength level which is ...

Using Lightweight Aggregate for Internal Curing Concrete ...

Sep 02, 2015  Lightweight concrete has long been used for suspended floors in order to reduce the weight on the structure and to increase the fire rating. And since a lightweight floor is typically thinner (5.25 inches versus 6.5 inches with normal weight for the equivalent fire rating), a lightweight floor will be 40% to 45% lighter than a normal-weight floor.

Advantages and Disadvantages of Lightweight Concrete ...

Jun 29, 2020  Specific types of lightweight aggregates make varying forms of lightweight concrete. These vary from lightweight aggregate concrete, foamed concrete, or Autoclaved Aerated Concrete (AAC). The aggregates used in AAC are extremely fine, even smaller than a grain of sand. This composition makes AAC highly suitable for pre-casting and reshaping.
