Lightweight Aggregate - an overview ScienceDirect Topics
Lightweight aggregate: Lightweight aggregate is often defined as any aggregate with a dry loose bulk density of less than 1200 kg/m 3. Lightweight aggregates are used to produce lower density concretes, which are advantageous in reducing the self-weight of structures and also have better thermal insulation than normal weight concrete.
