Abstract: The invention presents a non-metallic laminated composite reinforcing rod for use in reinforced or prestressed concrete. The rod is made by creating a sheet of core material (1) comprising a number of layers of "pre-preg" material. Ribs (2) are formed on top of the core from additional layers of pre-preg material laid with the fibers transverse to those in the core. The ribs (2) are then covered by additional layers of pre-preg (3) laid with fibers parallel to the core fibers. The material is heated to fuse the layers. Finally, the sheets of laminated reinforcement are cut parallel to the core fibers to the width desired. The resulting reinforcing rod (62) is superior to steel in corrosion resistance, flexibility, durability, and strength. The reinforcing rod (62) may be used as a prestressing tendon in prestressed concrete after encasing the ends of the rod in an attachment formed of a sleeve (60) filled with grouting material (63) such as mortar or epoxy. The glass-fiber embodiment is non-conductive. If carbon pre-preg made of high modulus fibers is used, then the Young modulus of the LCRs is approximately equal to that of steel.

Abstract: In a prestressing strand for use in stressing a concrete structure, having one or more central core wires and a plurality of outer wires extending helically around the core wire the surface of at least the core wires is modified in order to increase the friction resistance to relative movement between the core wire and the outer wires. This strand is found to give more accurate stressing, where the conduit in the concrete for the tensioned wire is curved. The outer wires may also have modified surfaces. The modification may be mechanical indentations or surface conditioning treatment such as oxidation, etching, coating or deposition.

Abstract: Steel materials for use with concrete that is prestressed by posttensioning are disclosed. In accordance with one embodiment of the invention, a steel member is sheathed with a heat-shrinkable synthetic resin tube. In another embodiment, the steel member is sheathed with a foamed synthetic resin tube. Both embodiments are further applicable to the case of a stranded steel member, in which case it is preferred that the spiral grooves of the stranded member be filled with a resin before sheathing with an external tube.

Abstract: The non-destructive monitoring of the integrity of reinforcements in parts of buildings and installations such as bridges, tunnels, concrete pavements, conveyor belts, etc., by means of magnetic field measurement is considerably improved by magnetising the reinforcements before their installation. A magnetisation up to the saturation point, of which there remains a remanent magnetisation after the magnetising field is removed, is particularly appropriate. Preferably, magnetisation is carried out "on the spot" at the building site by means of a device which has a magnetisation coil with a mains supply circuit for the adjustable energy supply and elements for holding and guiding the prestressing elements through the coil.
