Abstract
Water having alkalies selected from sodium, potassium and mixtures thereof dissolved therein is treated with a composition to reduce the concentration of the alkalies whereby the water is rendered usable according to ASTM standards to render the water usable as concrete mix water. The composition and the method of its use is disclosed herein, wherein the composition is selected from compounds in the group consisting of lithium carbonate, acid zirconium phosphate, carbon dioxide and mixtures thereof.
Claims18
A method of reducing the concentration of alkalies dissolved in an aqueous solution said method being comprised of the steps of:
- providing an aqueous solution having alkalies dissolved therein wherein said alkalies are selected from the group consisting of sodium, potassium and mixtures thereof;
- placing an effective amount of an additive in contact with said solution wherein said additive is a composition selected from the group consisting of lithium carbonate, acid zirconium phosphate and mixtures thereof;
- and
- maintaining said contact for a time sufficient to reduce said concentration of said alkalies dissolved in said aqueous solution.
A method of reducing the concentration of alkalies dissolved in an aqueous solution said method being comprised of the steps of:
- contacting said aqueous solution with an effective amount of an additive for a time sufficient to reduce said concentration of said alkalies dissolved in said aqueous solution from a first concentration to a second concentration;
- wherein said alkalies are selected from the group consisting of sodium, potassium and mixtures thereof and wherein said additive is a composition selected from the group consisting of lithium carbonate, acid zirconium phosphate and mixtures thereof.
