This paper presents the detailed investigation of the combined effect of the cementitious materials (Fillers) in the fresh and hardened properties of Self Compacting Concrete (SCC). The investigation includes blend of Ordinary Portland Cement (OPC) and Fly ash (FA) in which OPC is partially replaced with certain percentage of FA(25%, 30%, 35%, 40%, 45%).The Control mixture contained Ordinary Portland Cement (OPC) replaced with 20 % of Fly ash (FA) by the weight of OPC. The use of fillers (FA) reduced the hydration in cement and provides cohesion to the concrete. The total binder content of 550 kg/m3 and water binder ratio of 0.34 were taken as constant for all the mixes. This paper presents the experimental investigation of fresh properties like Slump flow test, L Box, U Box ,V funnel and T50 time and the Hardened properties in the strength aspects like Compressive strength, Split tensile strength and Flexure strength of beams for all the mixes were compared. Based on the results optimum replacement percentage of FA and flexural behaviour of beams was studied. But the mix with 35%FAexhibits better performance than all other mixes.
