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： A method is described for the electrochemical protection of reinforcement in concrete in harsh environments, for instance in contact with, or in close proximity to, seawater. On concrete a composition comprising graphite dispersed in a curable mineralic binder in the form of water glass or another water-soluble inorganic silicate, a dispersion agent, optionally together with conventional additives is applied. The application is performed by spraying or brushing. An impregnation is optionally performed, either concurrent with the application of the composition or thereafter. If necessary a post treatment is performed. Further, the use of the composition for electrochemical protection of reinforcement in concrete in connection with, for instance, quay constructions, bridges, bridge piers and similar constructions is described.

摘要： An image is reproduced and transferred onto a substrate by (a) providing a positive electrode having a continuous passivated surface moving at substantially constant speed along a predetermined path, the passivated surface defining a positive electrode active surface; (b) forming on the positive electrode active surface a plurality of dots of colored, coagulated ink representative of a desired image, by electrocoagulation of an electrolytically coagulated polymer present in an electrocoagulation printing ink containing a coloring agent; and (c) bringing a substrate into contact with the dots of colored, coagulated ink to cause transfer of the colored, coagulated ink from the positive electrode active surface onto the substrate and thereby imprint the substrate with the image. Step (b) is carried out by (i) providing a series of negative electrodes each having a surface covered with a passive oxide film, the negative electrodes being electrically insulated from one another and arranged in rectilinear alignment so that the surfaces thereof define a plurality of corresponding negative electrode active surfaces disposed in a plane spaced from the positive electrode active surface by a constant predetermined gap, the negative electrodes being spaced from one another by a distance smaller than the electrode gap; (ii) coating the positive electrode active surface with an oily substance to form on the surface micro-droplets of oily substance; (iii) filling the electrode gaps with the electrocoagulation printing ink; (iv) applying to the negative electrodes a bias voltage ranging from -1.5 to -2.5 volts; (v) applying to selected ones of the negative electrodes a trigger voltage sufficient to energize same and cause point-by-point selective coagulation and adherence of the ink onto the oil-coated positive electrode active surface opposite the electrode active surfaces of the energized electrodes while the positive electrode active surface is moving, thereby forming the dots of colored coagulated ink; and (vi) removing any remaining non-coagulated ink from the positive electrode active surface. The invention enables one to obtain an image resolution as high as 400 lines per inch, or more.

摘要： Reinforcement in concrete (1) is cathodically protected by galvanically connecting a sacrificial anode (3), such as a zinc or zinc alloy anode, to the reinforcement (2), and contacting the anode with an electrolyte solution having a pH which is maintained sufficiently high for corrosion of the anode to occur, and for passive film formation on the anode to be avoided. The pH of the electrolyte is preferably at least 0.2 units, more preferably from 0.5 units to more than 1.0 units above the pH value at which passivity of the anode would occur. The electrolyte may be for example sodium hydroxide or potassium hydroxide but is preferably lithium hydroxide which also acts as an alkali-silica reaction inhibitor.

摘要： Dans l'appareil et le procédé décrits qui servent à empêcher la corrosion de l'armature d'une structure armée, on dispose une ou plusieurs anodes (3) à proximité adjacente d'une surface de la structure (1) à protéger et on dispose un corps en matériau cimentaire iono-conducteur (6) autour des anodes pour qu'il entre en contact avec le matériau cimentaire iono-conducteur de la structure (1), le corps en matériau cimentaire iono-conducteur (6) étant entouré par une enveloppe (4) en matériau essentiellement non poreux résistant à l'humidité, destinée à maintenir ledit matériau (6) dans des conditions de conduction ionique. Les électrodes (3) et l'armature (2) se trouvant dans le corps (1) peuvent être connectées électriquement pour permettre le passage d'un courant à travers les deux sortes de matériaux cimentaires iono-conducteurs, de façon à protéger l'armature (2) contre toute corrosion électrolytique.

摘要： Electrically conductive valve metal mesh of extreme void fraction. In a most important aspect the invention relates to an application of the mesh as an electrode structure in such a way as to prevent the corrosion of steel, including reinforcing steel in concrete, by cathodic protection. To prepare the electrode structure, coiled metal mesh of the present invention is coated with an electrocatalytic coating from liquid composition. The coating operation can proceed by contacting the mesh with liquid coating composition while the mesh is maintained in coiled form. This highly efficient coating method is continued through a curing operation while further maintaining the coated mesh in coiled form. The coated mesh can later be uncoiled and current distributors welded to it for use as an electrode, e.g., in cathodic protection.
