INFLUENCE OF STEEL FIBRE REINFORCEMENT ON THE FRACTURE BEHAVIOUR OF CONCRETE INCOMPRESSION

Experimental results are presented to describe the compressive load-deformation characteristics of steel fibre reinforced concrete. The influence of steel fibre reinforcement on the fracture process of concrete is discussed, based on data for various volumes of melt extract, hooked, straight and crimped steel fibres. The results indicate that the primary effect of steel fibre reinforcement on the fracture behaviour of concrete up to ultimate stress is very similar to the characceristics imparted by coarse aggregate inclusions. The initiation and critical stress and strain values decrease with increasing fibre content and the volume of the crack phase in the matrix increases. Steel fibre reinforcement improves the energy absorption capacity of concrete due to the higher lateral strain capacity imparted by steel fibres and due to energy dissipation during pull-out of fibres which bridge tension and shear cracks in the failing matrix.
