Abstract

This article presents the first part of a study concerning the behaviour of ultra-high performance fibre concrete (UHPFC) under fire. Four kinds of synthetic fibres were added: polypropylene (PP), acrylic (PMMA), polyvinyl acetate (PVA) and polyethylene (PE). After mechanical and thermal characterizations of the material, blowtorch tests were performed on it. The expected efficiency of PP and PE fibres was observed. Microscopic observations enabled us to put forward a hypothesis regarding the efficiency of fibres in concrete.
