Lightweight Aggregate - an overview | ScienceDirect

1 Lightweight Aggregate Concrete. All kinds of light concrete that are made by light coarse aggregates, light fine aggregates (or ordinary sand), cement and water are known as lightweight aggregate concrete. According to the types of aggregates, lightweight aggregate concrete can also be divided into full lightweight concrete (both the coarse and the fine aggregates are light aggregates) and sand lightweight concrete (all or part of the fine aggregate

LIGHTWEIGHT AGGREGATE CONCRETE: EFFECT OF AGE

2015-1-12 · Lightweight aggregate concrete may be very different from normal weight concrete from this point of view. The properties mainly depend on the properties of the lightweight aggregate like particle density, water absorption capacity. The aim is to study the impact of the time under water storage on compressive strength and fracture tests results.
