    Abstract :

    Recycled concrete aggregates (RCA) are crushed, graded inorganic particles processed from the materials of concrete demolition debris. The aim of this research work is to study the behavior, in fresh and hardened states, of high strength structural concrete with recycled aggregates and synthetic fibres. The scope of this paper is to compare fresh and hardened state properties of high strength concrete by using various proportions of recycled coarse aggregates (0, 50% and 100% replacement of natural aggregates) along with PP fibres (0, 0.2, 0.3 and 0.4% by volume of concrete). The parameters of investigation include tests on workability, compressive, flexural and indirect tensile strengths, and modulus of elasticity. It is observed that the workability of concrete considerably reduced with the increasing quantities of recycled aggregate and polypropylene fibres. The results showed a gradual decrease in compressive strength, tensile strength and secant modulus of elasticity as the percentage of recycled aggregate used in the concrete mix increased.
