Lightweight Aggregate Concrete ScienceDirect
Lightweight aggregates are made by a thermal process using natural materials such as clay, shale, slate, perlite, and vermiculite. The production process of lightweight aggregate depends upon the raw materials used. Basically, there are two processes for making lightweight aggregates—a wet process and a dry process.
