interprets the data on lightweight-aggregate concrete from many laboratory studies and the accumulated experience resulting from its successful use, and reviews performance of structural light- ... Because much of the properties and performance of light-weight concrete are dependent on the type of LWA used, the ready mix supplier, LWA producer ...
Most of these aggregates are light in weight because of the pore structure developed within them during the production stage. Aggregate having a particle density less than 2000 kg/m 3 or dry loose bulk density of less than 1200 kg/m 3 is considered as lightweight aggregates (BSI 92/17688). Lightweight aggregate concrete has been …
Lightweight expanded clay aggregate (LECA) is a manufactured aggregate with many uses in construction, such as aggregate for the lightweight concrete or like geotechnical fill. The properties of the material may vary depending on the manufacturer or the applications envisaged for the aggregate.
