What is lightweight aggregate. Lightweight aggregate concrete (LWAC) is a type of concrete that uses lightweight aggregates as its main ingredient. These aggregates are usually natural materials such as pumice, vermiculite, and perlite. LWAC is often used as a substitute for normal concrete in applications where weight is a factor, such as in ...
