Lightweight Aggregate an overview | ScienceDirect Topics

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.
