Claim Text:
1. A method for treating a concrete structure, the method comprising: applying an amount of concrete treatment compound to an upper surface of the concrete, the concrete treatment compound comprising a mixture of a liquid carrier compound with a titanium dioxide (TiO 2 ) photocatalyst, the liquid carrier compound carrying the TiO 2 photocatalyst into the concrete structure, wherein the liquid carrier compound penetrates the concrete to a depth range of approximately an eighth of an inch to approximately a quarter of an inch, as measured from the upper surface of the concrete, so as to embed the TiO 2 photocatalyst therein, and simultaneously seals and hardens the concrete, and fills voids in the concrete so as to increase resistance of the concrete to deleterious effects, the application of the concrete treatment compound to the upper surface of the concrete causing a reduction of pollutants proximate to the concrete, the pollutants including nitrogen oxides and volatile organic compounds, the concrete treatment compound uniformly impregnating the concrete such that normal wear of the upper surface of the concrete exposes an underlying photocatalytic reactive layer of the concrete, so that a pollution-reducing capability of the concrete treatment compound is self-regenerated.
