Abstract: A reinforcing body and a method for its manufacturing. The reinforcing body has at least one reinforcing bar. Each reinforcing bar has a core with a peripheral surface at which a rib structure with at least one rib and at least one depression is provided. The core is formed by at least one first fiber strand embedded in a core matrix. For creating the at least one rib at least one second fiber strand is embedded into a rib matrix, wherein the at least one second fiber strand and the rib matrix are separated by at least one depression in a direction parallel to a longitudinal center axis of the reinforcing bar, such that the at least one second fiber strand is separated into fiber strand sections. The at least one first and the at least one second fiber strand have fibers of different materials.

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: 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.
