Plain Concrete exhibits brittle behaviour which is undesirable property for a structural material resisting dynamic forces. Using used tyre crumb rubber and steel cords extracted from used tyres as steel fibre reinforcement can enhance ductility and toughness of concrete which is environmentally beneficial and technically sound. In this study, 12.5% volume of Crumb rubber of maximum size passing sieve 4.75mm was used to replace fine aggregates and recycled tyre steel fibre (RTSF) dosages of 0.3%,0.6%,0.9% and 1.2% by mass of concrete were added in concrete to investigate flexural performance of the Recycled tyre steel fibre reinforced rubber concrete (RTSFRC). 24 Concrete beams (500x150x150mm) were manufactured to evaluate the effect of (RTSF) volume and its aspect ratios on flexural strength and Toughness of rubber concrete. The results showed that, combined crumb rubber and recycled tyre steel fibre from waste tyres improved the ductility and toughness of concrete.
