Using Lightweight Aggregate for Construction Material

Lightweight concretes date back to before the Roman Empire. The earlier concretes were made by combining a burnt lime for cementious material with pumice or volcanic rock for aggregate. Although structural value was limited due to its primitive nature, many structures were able to withstand the test of time. One of the most famous and largest concrete ships built through this program was the U
