ABSTRACT
Lightweight concretes have been successfully applied in the building constructions for decades because of their favourable material properties, especially their low specific weight in connection with a high strength, a high capacity of thermal insulation and a high durability. The development leading to a self compacting light weight concrete (SCLC) represents an important innovative step in the recent years. This concrete combines the favourable properties of a lightweight concrete with those of a self compacting concrete. Research work is aimed on development of (SCLC) with the use of light aggregates “Light expand clay aggregate (Leca)". In this investigation, first by trial and error, different mix design of SCLC were casted and tested to find out the values of slump flow, L-box, V-funnel and 28 day compressive strength. Based on the results obtained, the best so-called standard mix design was selected for further investigation. For two selected mix, engineering properties of SCLC, such as compressive and flexural strength, E-modulus, shrinkage and swelling (expansion) values for three different curing conditions were measured at short and long ages (upto-90 day).The results are shown that use of SCLC can improve the engineering properties as well as the durability of structural concrete made of light weight materials such as Leca.
