ABSTRACT Current advancements in the construction of cement and workability improving substitutes have made it simple for fabrication of concretes with high compressive strength. The scope of this study is to discuss the use of structural lightweight aggregate concrete and examine it potential utilizations. Lightweight concrete properties is discuss to have a prior knowledge about the structural lightweight concrete (LWC). The method of production, types, and characteristics of lightweight aggregates (LWA) used for structural purpose are presented. Production and main characteristic of concrete make from this aggregates were investigated........... Keywords:...........concrete, lightweight aggregate, lightweight concrete.
