A concrete's durability and mechanical strength can be affected by unoccupied spaces and macropores created by improper vibration and compaction, which can also be one of the reasons why concrete deteriorates. Okamura first developed Self-Compacting Concrete (SCC) in 1986, and it is a well-considered answer to the issues mentioned above. Concrete that compacts itself under its own weight is known as self-compacting concrete and requires no further effort to do so. Numerous studies have been conducted to examine the behaviour of plain SCC. Additionally, numerous studies from the past have shown that different fibres can be used to enhance the structural qualities of concrete. But here the combination of steel fiber and recycled concrete aggregates on the flexural behavior of SCC to be investigated. Steel fibres are added to concrete at several rates (0%, 0.5%, 0.75%, and 1%) and recycled concrete aggregate is used to replace coarse aggregate to a certain extent 25%. Cubes, Cylinders, Prisms and RCC beams were casted. Also founded the properties of fresh and hardened concrete. It had been found that the RCASF 3 mix performed better than the RCASF 1 and RCASF 2 replacement mixes. Results from the experiments and analytical were examined. Results from analytical are slightly lower to those from experiments.
