Structural Lightweight Aggregate Concrete| Concrete ...

Structural lightweight concrete also resists fire better than normalweight concrete because of its lower thermal conductivity and its lower coefficient of thermal expansion. In many structures, these benefits justify the use of lightweight aggregate concrete, which generally costs more than normalweight concrete.
