Lightweight Aggregate - an overview ScienceDirect Topics

Lightweight aggregates (LWA) are defined as construction materials that have a bulk density lower than that of common construction aggregates (Choudhry and Hadley, 2009). It is possible to manufacture LWA and ultra LWA from gasification slag and fly ash, according to

2021-8-25  Lightweight aggregates Our lightweight aggregates from Lytag® are made from fly ash generated by coal fired power stations. Our technology heats the fly ash to 1,100°C to create a hard pellet, with a honeycombed internal structure. Which can then be used as a superior, lightweight aggregate which is up to 50% lighter than natural aggregate.
