“…The good durability properties of ceramic fibres were proved by several researchers [1][2][3]. To name a few, Low and Beaudoin [1] reinforced cement composites by wollastonite fibres, Sugama et al [2] investigated calcium aluminate/fly ash/polyphosphate cements with ceramic fibre reinforcement and Yon et al [3] introduced new type of calcia/alumina fibres, which are produced by the process of inviscid melt spinning. Sugama et al [2] also showed superior properties of fibre reinforced composites when exposed to hydrothermal conditions.…”

This study is aimed at the evaluation of the behaviour of Portland cement based composites reinforced by ceramic fibres when exposed to higher temperatures. The main emphasis is given on the determination of influence of ceramic fibres, which are added in order to improve the post-heating maintenance of mechanical properties of studied composites. Ceramic fibres are, thanks to its origin, predestined to have good resistance to fire and high temperatures. Their influence is investigated through the way of experimental measurement performed on three mixtures varying in the amount of used fibres. Also reference composites without reinforcement are tested. Two sets of each material are made and exposed to different temperature conditions. Loading temperatures are set as 105°C and 400°C and studied properties are basic physical properties, mechanical parameters, liquid transport properties and diffusion characteristics. Results generally prove the beneficial effects of ceramic fibres on the mechanical properties and on the overall behaviour of the composites for both prior and post heating state.
