Different mix designs of cement based composites with a varying amount of rice-husk ash as a pozzolan, water-cement ratio and super plasticizer were investigated. Composite properties were then studied using the Slump-Flow test, L-Box test, V-Funnel test in order to evaluate bleeding, resistance to segregation and workability. The physical and mechanical properties of Self-Compacting Concrete (SCC) were studied and compared with a reference normal concrete (NC). 48 cubic moulds were made and their compressive strength at the ages of 3, 7, 14, 28, 60, 90 and 120 days determined. In this survey to determine tensile strength, shrinkage and modulus of elasticity, 12 prismatic moulds, 6 prismatic and 3 cylinders moulds were prepared. These samples cured in three different environmental conditions such as water, humidity and air. The results show higher compressive strength in SCC, while shrinkage does not differ from that of NC. We found that the modulus of elasticity and Poisson's ratio are slightly improved in SCC.
