Lightweight self-compacting concrete with light expanded clay aggregate (LECA)
Faculty of Engineering, Menoufia University, Menoufia, Egypt
Lightweight concretes have been successfully applied in building constructions for many years due to their favorable material properties, particularly their low specific weight in connection with a high strength, a high capability of thermal insulation and a high durability. The development leading to lightweight self-compacting concrete (LWSCC) represents an important advanced step within the recent years. This concrete combines the favorable properties of a lightweight concrete with those of a self-compacting concrete. Research work is aimed on development of (LWSCC) with the use of light aggregates “Light expanded clay aggregate (LECA)”. In this research, first by specific gravity factor method, twenty different mix designs of (LWSCC) were cast and tested to find out the values of slump flow, J-ring , V-funnel and 28 day compressive strength. Based on the results obtained, the best mix design was selected for further investigation. This paper also focuses on studying the effect of changing the reinforcement ratio on reinforced two way slabs when the dimensions were kept constant.
