Lightweight aggregates | Aggregate Industries
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.

The history of lightweight aggregates is the subject of another section. This discussion includes the development used by the Romans to construct the Coliseum (about AD 80) and the Pantheon (about AD 126). The various types of lightweight aggregates produced in the United Kingdom, their manufacture, properties and applications are described.
