| 2 | Method for removing salts and negative chloride ions from porous materials | US15023415 | 2014-10-01 | US20160214909A1 | 2016-07-28 | Jan Saelensminde |
| A method for removing salts from a porous material, using cyclical wetting and drying of the surface of the material. The basic idea of the method is to identify a salt that is desired to be removed from the material, along with its equilibrium moisture content. A piece of sheeting is placed on the surface of the material and the edges of the sheeting are sealed against the surface. Moist air is then passed inside the sheeting until the surface of the material has been wetted. Dry air is then passed inside the sheeting until the relative humidity of the air inside the sheeting comes below the equilibrium moisture content of the salt. Cycles of supply of moist air and dry air are repeated until a desired amount of salt crystals is formed on the surface of the material and the salt crystals are removed from the surface. | ||||||

| PURPOSE: To provide a low-cost electrochemical treatment of concrete characterized by discharging an electrolyte solution from nozzles to the surface of concrete and concurrently passing a current between external electrodes and/or between each of external electrodes and a specific internal electrode through applying a voltage between these electrodes. CONSTITUTION: The plural nozzles 6 made of a corrosion-resistant material such as Ti alloy, etc., are fixed to the supporting rod 7 so as to allow them to contact with the surface of the neutralized concrete 1 or to form some space between each of the nozzles 6 and the surface of the concrete 1 and used as the external electrodes. The reinforcing bar in the inside of the concrete 1 is fitted with a white covered lead wire and used as the internal electrode and connected to the AC/DC converter 2 through the lead wire. Thereafter, an electrolyte solution such as Ca(OH) 2 solution, etc., is transferred from the electrolyte solution tank 3 to the nozzles 6 through the pipe line 5 and discharged from the nozzles 6 under an about 0 to 5kg/cm 2 discharge pressure so as not to break the electrical connection. In this state, the switch of the AC/DC converter 2 is turned on to subject the concrete 1 to electrochemical treatment by passing an about 0.01 to 5A, peferably 0.2 to 5A current per 1m 2 of the concrete 1 between the electrodes for a prescribed time. Thus, the objective alkalinated concrete can be obtained. COPYRIGHT: (C)1995,JPO | ||||||

| PURPOSE: To eliminate the environmental pollution caused by the scatter of cellulose fibers and to drastically reduce the industrial waste after treatment by providing a non-contact part with the surface of concrete in a vessel contg. an electrolyte soln., arranging a a retaining material sucking up the soln. and applying a current between electrodes. CONSTITUTION: A non-contact part is provided to the frame of a vessel to release the pressure for introducing an electrolyte soln., and the structure of the vessel is simplified. However, since the soln. is leaked from the non-contact part and the water level is lowered, the level lowering is prevented by using a retaining material (e.g. wood, felt). The height sucked up by the retaining material is preferably controlled to $10mm. An alkaline or neutral soln. (e.g. an aq. soln. of alkali metal salt) is preferably used as the electrolyte soln., however an weakly acidic soln. at ≤pH5 is also used. The sectional view of the vessel to be used is shown in the figure, and the concrete 1, vessel 2, non- contact part 3, electrodes 4, retaining material 5, water level 6 of the soln. and reinforcing bar 7 in the concrete are shown, respectively.

| PURPOSE: To remarkably increase the reforming effect of concrete by heating the surface and/or surroundings of the concrete in a method for reforming the concrete by impressing current between an external electrode provided on the surface of the concrete and the steel in the concrete as an internal electrode. CONSTITUTION: At least a part of the concrete to which current is impressed is heated by supplying steam or a heated electrolyte solution to the surface and/or surroundings of the concrete and further providing a heating element. In the case of supplying steam, the generating pressure of steam is preferably 1-10kg/cm 2. And in the case of supplying the heated electrolyte solution, the concrete is rapidly reformed since the temp. of the concrete is kept at 20-60°C. In the electric heating element, the quantity of electric energy is optionally and accurately controlled. The raised temp. is preferably ≥30°C. The impressed current for the purpose of removing salt matter in the concrete or recovering alkalinity is preferably 0.5-5A/cm 2 per the surface area of the concrete. COPYRIGHT: (C)1995,JPO | ||||||

| PURPOSE: To provide a method for modifying concrete, capable of electrochemically treating concrete containing a steel material in the interior. CONSTITUTION: A steel material in the inside of concrete is used as an internal electrode and electrodes installed in one or more places on the surface of concrete is used as an external electrode and an electrolytic solution retaining material consisting of sheet-like moldings and/or a fabric-like substance is installed around these external electrodes and electric current is made to flow between these external electrodes and/or between the external electrode and the internal electrode. Then, an electrolytic solution retaining material containing a water-absorbing substance and/or a swelling substance is used as the electrolytic solution-retaining material. Thereby, modifying effect of the concrete is sufficiently pulled out and simultaneously danger in operating and bad influence on peripheral circumstance can be reduced.
