1. 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.
