Abstract: Durability of concrete is in a great extent determined by the crack formation in a structure. Through the cracks water and other aggressive products can infiltrate in the concrete resulting in a deterioration of the concrete and/or corrosion of the reinforcement bars. As a result it can be concluded that the durability of a structure increases significantly when crack widths are limited. In addition some structures such as watertight structures require strict limits for the crack widths. Steel fibre reinforced concrete is generally known to reduce crack widths because of its post-cracking tensile strength. In the framework of the Brite Euram project BRPR-CT98-0813 19 full-scale SFRC beams containing ordinary reinforcement have been tested at the Department of Civil Engineering of the Catholic University of Leuven. The main investigated parameters were the fibre dosage, the fibre type and the amount of longitudinal reinforcement. For each beam the crack propagation history, i.e. crack widths at different load levels and final crack spacing, was recorded. The measured crack widths and crack spacing were compared to predicted values using the calculation method of RILEM TC 162-TDF and using a calculation model for crack widths developed by the authors.
