The experimental investigations were carried out on self-compacting concrete (SCC) to study the influence of basal fibre and recycled concrete aggregate (RCA) through mechanical and durability tests. The percentage of recycled concrete aggregate replacement was varied as 0, 50 and 100% whereas the basalt fiber was varied as 0, 2 and 4 kg/m3. The compressive strength of mix having nil RCA and 2 kg/m3 fiber was found to be increased up to 11.5%. The split tensile strength of mix having 50 RCA and 4 kg/m3 basalt fiber was found to be increased 27% as compared to conventional SCC. The maximum value of flexural strength was observed for R50B2 which was 22.05% more than the plain concrete. 100% replacement of RCA decreased the strength and the lowest was found in R100B0, which was 42.64% lower than the conventional concrete. It was observed that the carbonation depth of concrete was found to be increased with the increase of recycled concrete aggregate as well as basalt fiber. When recycled concrete aggregate alone was introduced, in 28 days of exposure period the carbonation depth increased to 16.67% in the case of 100% replacement of recycled concrete aggregate. Best result was shown by the control mix only and the worst result was noticed in R100B4 which was 50, 71.4 and 84% more than control mix in 28, 56 and 90 days respectively.
