Abstract
The present invention relates to a method for impregnating concrete with a non-aqueous electrolyte characterized in that an electric field is applied between electrodes mounted on the concrete surface and/or embedded in the concrete such that the non-aqueous electrolyte migrates into the concrete. Preferably, lithium ions are dissolved in the non-aqueous electrolyte.
Claims18
A method for impregnating concrete with a non-aqueous electrolyte, comprising
- applying an electric field between electrodes mounted on a surface of the concrete and/or embedded in the concrete such that the non-aqueous electrolyte migrates into the concrete,
- wherein the non-aqueous electrolyte absorbs water and is hygroscopic, and
- wherein the the non-aqueous electrolyte comprises polyethylene glycol.
Method for impregnating concrete with lithium ions, comprising applying an electric field between electrodes mounted on a surface of the concrete and/or embedded in the concrete, wherein at least one electrode, comprising the anode, is embedded in a non-aqueous electrolyte comprising polyethylene glycol, such that lithium ions migrate into the concrete.
