Heterogeneous characteristics of concrete with variation in strength of matrix, aggregate and interface causes non-uniform distribution in stress. Reinforcing concrete alters this distribution and can be designed to reduce non-uniformity. Present study investigates applicability of plastic strips as reinforcement to improve performance of concrete. Since plastic strips are strong in tension, they are oriented to control tensile stress generated in concrete. The approach adopted contributed to increment in compressive strength of fibre reinforced concrete. In comparison with conventional concrete, fibre reinforced concrete has higher but delayed compressive strength, lower initial stiffness and higher energy absorption capacity.
