This paper reports on the fundamental findings of utilizing Styrene Butadiene Rubber (SBR) waste tyre granules as a potential source for replacing coarse aggregate in elastomeric modified concrete (EMC). EMCs incorporating 2%, 4%, 6% and 10% of SBR granules (12-15 mm) are assessed for their fresh and hardened properties compared to control concrete devoid of SBR granule additions. Fresh concrete was investigated for slump, air content, and wet density while hardened concrete was evaluated for compressive strength at 7, 28 and 56 days of age. A decrease in slump, density up to 4% and compressive strength of 10 to 44% for 28 days of age, with the addition of SBR granules and an increase in the value of air content were observed.
