Abstract

The durability of concrete has been studied ever since it was first used. Researchers have incorporated several materials to make concrete strong and durable. This research focuses on the infusion of styrene butadiene rubber polymer (SBR) as a partial replacement of cement and studies its effects on fresh and hardened properties of concrete. Samples were prepared using partial replacement of SBR in proportions of 0%, 5%, 10% and 20%. Results showed that the fresh density of concrete decreased with the addition of SBR whereas the trends of workability showed an increase with cement replacement. Compressive strength increased at lower percentage replacements however the flexural and tensile strength increased till 15% SBR addition after which it decreased. The total porosity in terms of water absorption decreased which makes SBR modified concrete feasible for concretes exposed to moist conditions and the decreased porosity would increase its durability against chloride induced corrosion.
