Fibre reinforcement is one of the effective ways of improving the properties of concrete. However, current studies on fibre-reinforced concrete (FRC) have focused mainly on reinforcements with steel and glass fibres. An experimental programme on the properties of various synthetic fibre reinforced cementitious composites and the properties of the reinforcing fibres is described. Acrylic, polyester, and aramid fibres were tested in uniaxial tension, both in their original state and after ageing in cement. Samples of these fibres were found to lose varying amounts of strength with time, depending on the ageing temperature. Two different test methods were used to measure the fibre--cement interfacial bond strength. The tensile properties of concrete reinforced with acrylic, nylon, and aramid fibres, in the form of random distribution or uniaxial alignment, were studied by means of three different tests: compact tension, flexural, and splitting tensile tests. The properties of concrete, particularly that of apparent ductility, were found to be greatly improved by the inclusion of such fibre reinforcement. 26 ref.--AA
