ABSTRACT
The present study deals with an investigation of the effects of low volumes of fibrillated polypropylene fibre reinforcement on the properties of concrete, in particular, on impact resistance. The main conclusions are:
1) The various types of commercial polypropylene fibres evaluated in the present study exhibited good bond with the matrix. However, in spite of the favourable bond, a low content of polypropylene fibre reinforcement (0.1 to 0.5%) had only a small positive influence on the impact resistance of both normal and high strength concretes.
