Abstract
This paper shows the results of three-point-bending tests performed on fibre-reinforced concrete (FRC) beams with controlled location and orientation of fibres.
The addition of fibres in concrete improves the flexural toughness, however it also introduces inhomogeneity in the material which causes higher spread of results when testing material properties. The overall performance of the material is dictated by the presence of fibres bridging the crack and therefore aspects such as their location and orientation play a crucial role.
The aim of the proposed research is to quantify how the location and the orientation of fibres with respect to the fractured surface affect the flexural toughness of fibre-reinforced cement-based materials.
To this end, a number of beams with different fibre-configurations have been tested, in particular by changing fibre location and fibre density. This paper shows the preliminary results of these experiments, and it discusses the issues encountered in the laboratory procedures.
