Abstract: A concrete component has a concrete matrix (49) and at least one non-metal reinforcing element (50), which can be shaped and at least one reinforcing part (29). The at least one reinforcing part (29) has a plurality of reinforcing threads (34) or reinforcing yarn arranged in a plastic matrix of a plastic (K). The plastic (K) is designed to be reversibly cross-linked. The cross-links can be released by heating the plastic (K) and reestablished by cooling the plastic back down. Thus, it is possible to produce and store a reinforcing element in completely hardened form as a standard element. In one application, the produced reinforcing element can be reshaped into the desired shape by releasing the cross-links in one or more locations, reshaping the reinforcing element, and then hardening the reinforcing element again by reestablishing the cross-links.

Abstract: The invention refers to the use of a parent solution (A) during a method for producing fibers for a fiber fleece by a so-called solution blow spinning. Water is used as solvent for the parent solution (A). At least one water-soluble polymer and preferably exactly one water-soluble polymer is dissolved in the water of the parent solution (A). The parent solution (A) additionally contains at least one surfactant and optionally plasticizer for the used at least one polymer respectively. By means of a parent solution (A) it is possible to produce fibers (24) by solution blow spinning.

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.
