Abstract
A concrete element with improved fire resistance having a textile reinforcement, such as carbon fibers. The concrete covers the textile reinforcement around 10 to 25 mm, the concrete being made from binding agents based on geopolymers or calcium-aluminate cements or Portland cement or blast furnace cement combined with an increased concentration of more than 2 kg/m3 polypropylene fibres and high temperature resistant aggregates. The textile reinforcement with fibers/filaments are impregnated with an impregnation mass/resin, ensuring, even at very high temperatures, a transmission of force between the fibres and the impregnation mass and protecting against the entry of oxygen. It also contains an organic faction of, for example, a maximum of 20 wt. %, wherein the impregnation masses being used, have a filler which is stable at high temperatures in an added amount of, for example, at least 12.5% in the form of particles.
