| abstract |
The invention relates to a concrete element with improved fire resistance and having a textile reinforcement, preferably made from carbon fibers. The concrete covers the textile reinforcement typically 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. It comprises a textile reinforcement with fibers/filaments that are impregnated with an impregnation mass/resin, the impregnation mass ensuring, even at very high temperatures of for example up to 1000°c, 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 20wt. %, 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. |
