Abstract

This article deals with a para-aramid fibre-reinforced composite based on Portland cement and is exposed to a high temperature loading. The main emphasis is on the residual properties after a temperature loading (of up to 1000°C). Two basic mixtures were designed, the first without para-aramid fibres and the second with them. The studied materials were exposed to three different temperature loadings and then a group of physical characteristics was determined. The designed fibre-reinforced composite could find its application as a material that improves the fire resistance of constructions, for example as boards for tunnel lining, or anywhere where a higher fire hazard or a higher temperature loading is present. Keywords: para-aramid fibres, concrete, high temperature, residual properties.
