Structure of Cellular Lightweight Concrete. Cellular Lightweight Concrete contains , Fly ash and Cement. First is : The is generated from generator and it produces by using an appropriate agent. The air is maintained at 40 to 80 percent of total volume. The size of differs is from 0.1 to 1.5 mm in diameter.
19. Entrained Air As with normal-weight concrete, entrained air in structural lightweight concrete ensures resistance to freezing and thawing and to deicer applications. It also improves workability, reduces bleeding and segregation, and may compensate for minor grading deficiencies in the aggregate.

Autoclaved Aerated concrete blocks Surface texture of AAC. 15. No – fines concrete: It is a type of light weight concrete produced by omitting the fine aggregates from conventional concrete. This concrete has only cement, coarse aggregate and water. Due to absence of fine aggregates, concrete will have large voids, resulting in light …
5. 5 lightweight aggregates. Other lightweight concretes may contain some normal weight sand. The compressive strength of these concretes covers an even broader spectrum, with structural lightweights at 6000 psi and higher at one extreme, and cellular fill concretes at 5 psi at the other extreme Lightweight aggregate concrete is usually …
Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates.
