    摘要: Process for the electrochemical treatment of a construction comprising a porous medium, a corrodible substance disposed in the porous medium, the construction having electrically conductive properties, comprising the application of an external electrode (3) to a surface (2) of the construction, the external electrode (3) being connected to a terminal of a generator (6), the porous medium being connected to another terminal of the generator (6), and the application of the following four phases at least once: during a first phase lasting between 12 and 360 hours, passing a negative electric current which causes anions to migrate from the porous medium to the external electrode (3) and cations to migrate from the external electrode (3) towards the porous medium, then during a second phase lasting between 2 minutes and 100 hours, interrupting the circulation of the electric current, then during a third phase lasting between 2 minutes and 24 hours, passing a positive electric current, then during a fourth phase lasting between 1 and 120 minutes, interrupting the circulation of the electric current.

    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 fibers produced by blowing, pressing, weaving or knitting so that the fibers lie in almost every direction, and wherein the fibers are of different thickness, 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 process for the electrochemical realkalization of reinforced concrete comprises passing a direct electric current between an anode associated with a layer of alkaline electrolyte applied to an external surface of the concrete and a cathode which is located internally in the concrete. The process causes the internal pH of the concrete to increase and a surface layer of the concrete to be impregnated with the electrolyte solution and which comprises a solution of potassium carbonate of concentration at least 0.3 Molar. The process may be applied to concrete a zone of which has a pH of less than 10.0 and the process continued until the pH reaches a level of at least 10.5, preferably at least 11.0.

    摘要: A method of making a cast concrete stepping stone whose exposed upper surface has the appearance of two or more grouted attractive natural stepping stones. A liquid release agent is applied to the mold which is then placed on a vibrator table and filled with wet concrete. The mold is vibrated for about 30 seconds and the surface of the concrete troweled smooth. Dry body color is sprinkled over the concrete surface and troweled to completely cover the concrete. A dry release agent containing powdered color having a darker shade than the body color is sprinkled over the dry body color covering the concrete. The desired pattern is then pressed into the surface of the concrete and after a six hour drying time, the cast stepping stone is removed from the mold. Excess body color and release agent are washed away and the washed surfaces totally dried. Finally a clear concrete sealer is applied to the exposed upper surface of the concrete stepping stone.
