Abstract

Quantitatively concrete occupies the largest volume in any modern construction activity and it is expected that there will be no substitute for concrete in the near future. Since such high volumes of concrete are being used for new construction, it is imperative to produce good quality concrete that will be durable with enhanced mechanical properties to maximize the service life of a structure. Though good concrete can be produced using automation and controlled environment, it is not possible to alter its inherent brittle nature and the lack of any tensile strength. In this context, fibre reinforced concrete (FRC) seems to be a viable alternative. The present study focuses on feasibility of using polypropylene fibres as secondary reinforcement to concrete to change its brittle nature. Accordingly, various percentages of polypropylene fibres were added to concrete and a series of laboratory experiments were conducted to investigate the use of polypropylene FRC in rigid pavements. Mechanical properties of concrete such as compressive strength, modulus of elasticity, flexural strength and toughness, abrasion and impact were determined. Except for abrasion, polypropylene fibres improved the mechanical properties of control concrete and 0.6% by volume was found to be the ideal fibre dosage.
