Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : The advantage of steel fibres in cement based materials vis-à -vis mechanical reinforcement is widely recognized in the field of construction. This paper considers the behaviour of materials under extreme conditions in terms of temperature (e.g. fire). To this end, a comparison is made of the mechanical behaviour of mortars reinforced with steel fibres, polypropylene fibres and a hybrid fibre combination. These mortars are subjected to various heat exposures and then tested mechanically. Protection mechanisms of steel fibres and polypropylene are analyzed. SEM observations of steel fibres show oxidation at high temperatures; this oxidation impairs the protective effect of steel fibres.
