This study focuses on the development and assessment of greener and sustainable mix of self-compacting rubberised concrete (SCRC) utilising commonly available waste materials such as fly ash, worn tires, and polyethylene terephthalate (PET) drinking bottles as fibres. Ten mixes containing ground tire rubber and PET fibres were investigated under compression, split tension, and flexure. In 05 out of 10 mixes, SCRC contained 35% fly ash by mass substitution of cement and ground tire rubber to substitute 0, 5, 10, 15, and 20% masses of fine aggregates. The remaining 05 mixes of SCRC contained a fixed 2% volume fraction of PET fibres measured by the volume of concrete. The compression, split tension, and flexure tests were performed at 28 days to assess the effects of ground tire rubber and PET fibres on the strengths, compressive stress–strain behaviour, and load–deformation behaviour. The results indicated that the replacement of 15% mass of fine aggregates with ground tire rubber is optimum without impairing the strengths of concrete. The PET fibres played a role in stabilising and improving the post-peak response in the compression and the flexure. Overall, the use of ground tire rubber as fine aggregates and PET fibres as reinforcement in concrete improved the response of concrete in compression and flexure.
