Types of Lightweight Concrete 1. Lightweight Aggregate Concrete. In the early 1950s, the use of lightweight concrete blocks gained acceptance in the UK for load-bearing inner leaf of cavity walls. New types of artificial lightweight aggregates (LWA) paved the way for introducing lightweight concrete (LWC) suitable for structural work.

GB/T 17431.1 [48] identifies the requirement of lightweight aggregate on the basis of loose bulk density and cylinder crushing strength. AACP aggregates can be classified as the lightweight artificial aggregate as bulk density ranges between 593.12 and 765.93 kg/m 3, which is below 800 kg/m 3 (refer Fig. 13). Increase in binder content led to ...

The production of lightweight aggregate (LWA) from industrial byproducts is one of the methods for safe and massive disposal. The production and use of lightweight aggregate (LWA) in the construction industry is not a new concept. The evidence regarding the utilization of lightweight aggregate can be obtained from ancient civilizations.
