摘要：Self compacted concrete is a innovative concrete that does not required any vibration or compaction forplacing. It is able to flow under its own weight even in the presence of congested reinforcement. Mix Design wascarried out for M30 grade concrete as per the Guidelines of EFNARC. This paper presents an experimentalinvestigation on strength aspects like compressive and split tensile strength of self-compacting concrete using recycledconcrete aggregate and workability tests like (slump, L-box, J-ring, V-funnel and V-funnel T50) are carried out. In thisstudy water to powder ratio is kept constant at 0.33. In this study, Natural aggregate is partially replaced with Recycledconcrete aggregate by10%, 20%, 30%, and 40% and Fly are replaced 25% for all mix for reducing the cost. To reducethe water absorption of recycled concrete aggregate, RCA submerged in water for 24 hours and used after saturatedsurface dry condition. The results of present study recommend SCC marginally achieves required compressive strengthup to 30% replacement of Recycled concrete aggregate.
