Comparison between mechanical properties of SCC containing Rice-Husk Ash and normal concrete

In this article we investigated different mix designs of concrete which has the various amount of Rice-Husk Ash as a pozzolan, water-cement ratio and super-plasticizer. Then we tested properties with the Slump-Flow test, L-Box test, V-Funnel test in order to evaluate bleeding, resistance to segregation and workability. To survey physical and mechanical properties of Self-Compacting Concrete (SCC) and compare with a reference normal concrete (NC), we used 48 cubic moulds to determine their compressive strength at the age 1, 3, 7, 14, 28, 60, 90 and 120 days. 12 prismatic 5 x 5 x 30 cm moulds, 6 prismatic 7 x 7 x 30 m and 3 cylinders 15 x 30 m moulds are prepared to approach their tensile strength, shrinkage and Modulus of Elasticity subsequently in required ages. These samples cured in three different environmental conditions such as water, humid and air. The results show higher compressive strength in SCC, while shrinkage does not differ with that of in NC. We can also find out that the Modulus of Elasticity and Poisson's ratio are almost higher in SCC.
