    摘要: There is described a method of cathodic protection, electrochemical chloride extraction and realkalisation in reinforced concrete or similar materials, and also reinforcement and crack prevention in concrete (1), comprising the impressing of a direct voltage between the reinforcement in the concrete (1) and a conductive device which is brought into contact with the surface of the concrete (1), and wherein the crack preventing effect is obtained by embedding the device in fresh concrete. The method is characterised in that as conductive device/current distributors there is used a mat (3) of optionally coated, conductive carbon fibres produced by blowing, pressing, weaving or knitting so that the fibres lie in almost every direction, and wherein the fibres are of different thicknesses, wherein the mat further comprises electric conductors (4) in the form of bands or wires of conductive material which are placed over or under the mat (3) or are incorporated therein.

    摘要: The invention relates to a method for removing an ionic impurity from building structures comprising the steps of: forming at least one electrode unit (2, 3) by mixing a clay compound with an ion exchange component; placing at least one anode (4) and at least one cathode (5) at the same or separate poultices (8); providing a buffer by applying a carbonate to the poultice (8) at the anode (4) and providing a buffer by applying an acid to the poultice (8) at the cathode (4); position one or more poultices (8) at the building structure (1); and apply an electric current to the electrodes (4, 5). The invention further relates to a device for removing an ionic impurity from building structures, the device including electrode units (2, 3) consisting of at least one electrode being an anode) (4) or a cathode (5) and at least one buffer component arranged in a poultice (8) including an ion exchange component.

    摘要: Pour régénérer un ouvrage (1) en béton armé, on applique contre sa surface extérieure (3) une réserve (4) de solution électrolytique basique capable de migrer au sein du béton, et on raccorde une liaison (6) électriquement conductrice entre les armatures (2) du béton et une électrode extérieure (5) en contact avec la réserve de solution électrolytique, cette électrode présentant une électropositivité différente de l'électropositivité des armatures. Il apparaît ainsi d'une part un courant osmotique de diffusion entre la réserve de solution électrolytique et l'eau interstitielle du béton, et d'autre part un courant électrique spontané qui circule dans la liaison électriquement conductrice.

    摘要: The corrosion of ferrous-based metals imbedded in concrete containing a chloride is inhibited by drawing the chlorides away from the metal, and then applying a composition containing ammonium carbamate or ammonium carbonate to the concrete. An agent may be added to the solution to prevent any calcium hydroxide contained in the concrete from precipitating the corrosion inhibitor.
