Embodiment Construction

[0024]The present invention addresses the aforementioned disadvantages by providing an improved layered concrete slab, and by providing an improved method for preparing a layered concrete slab. In the most simple terms, the concrete construction includes a base layer of traditional concrete utilizing a traditional cement, and a second upper layer of concrete containing photocatalyst particles upon the first layer of concrete. Preferably, the base layer of traditional concrete is much thicker than the upper layer of concrete containing photocatalyst particles.

[0025]With reference to FIGS. 1 and 4, a first method of producing the two layer concrete construction of the present invention comprises the initial step 10 of preparing subgrade or formwork for concrete placement. It is envisioned that the present invention will most often require the preparation of the subgrade for creating substantially horizontal surfaces such as for walkways, driveways and the like. However, the present in...

Abstract

A concrete slab construction is provided for use in both horizontal and vertical structures. The slab construction includes two layers. The first layer of concrete is a base layer comprised of traditional concrete materials. In addition, the concrete slab construction includes a second exterior layer of concrete which contains photocatalyst particles. Preferred photocatalytic materials include titanium dioxide in the anatase form. The concrete slab construction provides for reduction of green house gases and reduction in organic stains.

Description

[0001]The following patent application claims priority to U.S. Provisional Patent Application No. 61 / 685,323 filed Mar. 16, 2012 and U.S. Provisional Patent Application No. 61 / 739,519 filed on Dec. 19, 2012.BACKGROUND OF THE INVENTION[0002]The present invention relates to concrete constructions, and more particularly to methods for producing concrete constructions.[0003]Concrete is a well known building material for commercial and residential applications. Concrete is durable, has good weight resistance, and provides excellent cost economy. Recently, concrete has become used more and more for flooring applications, but also for other structural applications which are highly visible to the public. Because of its widespread use, it is desirable to provide different colors and surface textures for the concrete. Well known techniques for improving aesthetics include adding color to the concrete. Other aesthetic techniques include modifying the surface texture of the concrete by implorin...
