Multi-layered cement compositions containing photocatalyst particles and method for creating multi-layered cement compositions containing photocatalyst particles

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...

AI Technical Summary

Benefits of technology

The patent describes a method for creating a concrete slab that has photocatalytic properties, which means it can break down polluting substances and organic stains when exposed to light, oxygen, and water. This is accomplished by adding a layer of concrete containing additional photocatalytic particles, such as titanium dioxide or one of its precursors, to the already existing layer of traditional concrete. The resulting slab is a multi-layered construction with increased aesthetic and photocatalytic properties that can help reduce greenhouse gases and remove organic stains.

Problems solved by technology

Unfortunately, the cement with photocatalyst properties is not suitable for conventional structural concrete projects such as walkways, walls, water features etc.
