That ordinary concrete used in reinforced concrete structures has high unit weight is one of the undesirable properties of this concrete. Since large part of the loads on structure consist of self weight of structure or structural members. Therefore, this situation becomes problem during passing of large spans and construction of high structures. In addition these structures are excessively affected by earthquakes because of their high self weight. On the other hand, it is well-known that ordinary concrete has high thermal conductivity and this increases heating expenses. Under the circumstances, main purpose of this study is to investigate advantages, disadvantages of lightweight concrete compared to ordinary concrete. In addition, producing, placing, properties, importance, future and application of lightweight concrete are explained. Finally some conclusions and recommendations inferred from this study are given.
