In some applications of steel fibre reinforced concrete (SFRC), structural behaviour depends on the post-crack strain characteristic of the concrete. The durability of fibres in this case can be of great influence for the stability of the system. Whereas durability of fibres in cracks of concrete under chloride influence cannot be ensured, the behaviour of steel fibres in carbonated cracked concrete is hardly known. This paper presents results on the corrosion behaviour of different types of steel fibre in carbonated cracked SFRC-beams under outdoor conditions, showing that under unfavourable conditions, corrosion of fibres in the cracks can affect the durability of the SFRC. Keywords: Carbonation, Cracks, Corrosion due to carbonation, Durability structural assessment, Steel fibre reinforced concrete (SFRC). Professor Dr.-Ing. Peter Schiessl is Director of the Institute for Building Materials Research at the Technical University of Aachen. Besides other fields of activities he is working in the field of durability and repair of concrete structures with particular reference to corrosion of steel in concrete. He is active in CEN-, CEB-, RILEM-and various national committees. Remain Weydert is a Research Engineer at the Institute for Building Materials Research at the Technical University of Aachen. He is specialised in corrosion of reinforcing steel and steel fibres in concrete and in corrosion protection.
