Abstract: The invention relates to a method for producing a coated basic material for a hydraulic composition (11) comprising a basic material (14, 16) and water (15). According to the invention, the basic material can consist of several sub-groups (14, 16) and at least one hydraulic binding agent (14) and to produce the hydraulic composition the basic material (14, 16) and the water (15) are mixed in a mixer (8). Prior to the mixing of the hydraulic composition, the basic material (14, 16) is at least partially coated with an additive (13). The invention also relates to a coated basic material to be used in concrete production, to an additive for concrete production and to a method for producing a hydraulic composition.

Abstract: The invention relates to a prefabricated construction element for buildings in prefabricated construction, comprising a core element (10) and at least one reinforcement element (12). In order to absorb high tensile and transverse forces without the danger of developing cracks, the reinforcement element is configured as a flat material element (12) from fiber-reinforced plastic that is fixated on a lateral face (20) of the core element (10) in a form-fit and/or a material fit.

Abstract: The invention relates to a reinforcing bar for mineral building materials, particularly for cement. The inventive reinforcing bar (10) is made of a bar of plastic material reinforced by fiber, which has a central, elongate core (12) and several ribs (14) which extend along the length of the core, which are disposed at an angular distance from each other, which form a cross or a star in the cross section thereof and which are twisted around the core axis (16) in a helical manner.

Abstract: The invention relates to a reinforcing device for supporting structures, that comprises a lamellar structure that runs into an anchoring device. Said lamellar structure is composed of a plurality of separate or separable individual layers between which intermediate layers are disposed at least in the zone of the anchoring device. The invention also relates to a method for producing such a reinforcing device and to a method for the reconstruction and/or reinforcement of edifices on the basis of such a reinforcing device. Preferably the lamellar structure is provided with carbon-fiber reinforced plastic lamellae (CFK) as the individual layers which are imbedded in a thermoplastic matrix. Preferably the individual layers of the lamellar structure are based on a thermoplastic conventional plastic material and additionally have interposed fabric inserts of metal plates as the intermediate layers, most preferably a bidirectionally oriented fabric, especially a bidirectionally oriented aramide fiber fabric.

Abstract: A method for fastening a flat strip lamella (10) to the surface of a building component (12). According to the inventive method, the face (14) of the flat strip lamella (10) is pressed against the surface of the building using an adhesive coating (16) consisting of a reaction resin applied in a paste-like consistency (16) and hardened to form an adhesive joint. The flat strip lamella (10) comprises a plurality of carbon fibers which are embedded in a binder matrix (28) and placed parallel to each other in a longitudinal direction. In order to increase the speed at which the adhesive coating hardens, the invention provides that an electrical current flows through least one part of the carbon fibers (26), heating the flat strip lamella (10) which in turn heats the adhesive coating (16).

Abstract: Flat strip lamella for reinforcing weight-carrying or weight-transferring building components. It has a composite structure consisting of a plurality of pliant or loose-flex supporting fibers (26) aligned parallel to each other, and a binding matrix (28) which connects the supporting fibers to each other so that they are shear-resistant, and is fastenable by means of an adhesive (16) by its broad side to the surface of the building component (12) that is to be reinforced. So that the flat strip lamella, to which the binding matrix gives rigid elastic form, can also be bent over corner edges of a building component (12), the invention proposes that the binding matrix (28) be removed, in at least an intermediary area (30), by uncovering the supporting fibers (26), and that the uncovered supporting fibers be subjected to a liquid or pasty thermosetting plastic, in order to stabilize the bent-over condition.

Abstract: Flat strip lamella (10) for reinforcing load-bearing or load transferring building components e.g. concrete, wood, steel, natural stone or masonry. The flat strip lamella (10) has a composite structure consisting of a plurality of parallel aligned, bendable or flexible carrying fibers (26) and a binding matrix (28) joining the carrying fibers to each other and making them shear resistant. The lamella can be attached facewise to the surface of the building component to be reinforced, using adhesive (16). In order to be able to bend the flat strip lamella over corner edges of a building component, the binding matrix (28) consists of a thermoplastic synthetic material.

Abstract: The invention relates to a reinforcement element (8) for load-carrying or load-transferring structural parts (12). Said reinforcement element has a flat strip segment (100, consisting of a plurality of supporting fibers (26) which are embedded in a binder matrix (28) and are aligned parallel to one another and in the longitudinal direction of the segment. According to the invention, the flat strip segment (10) engages in an anchoring strap (18) with each of its free ends and is secured on said anchoring straps against the tensile and shearing forces exerted in the longitudinal direction of the segment. This enables the flat strip segment (10) can be fixed to a structural part (12) with an impressed pre-stress. The anchoring straps (18) can be anchored on the structural part (12) by means of fixing members (36).

Abstract: An injection hose intended for sealing expansion joint in concrete structures. The hose is in the form a continuous hollow extrusion (12), made of elastic, flexible material, with a continuous longitudinal bore (10) and at least one longitudinal groove (16). The groove (16) is connected to the bore (10) by means of apertures (22) in the wall of the extrusion and is fitted with a sealing strip (24), made of compressible, elastic material, which extends over the apertures (22). Production of the hose is made particularly simple and inexpensive by virtue of the fact that the width of the groove openings (26) is less than the diameter of the sealing strip (24) and that the means of holding the sealing strip (24) in place are formed by making undercuts in the side (30) of the groove (16).
