US Classification:

106638, 427344

Abstract:

The invention relates to a composition and method for effectively increasing the hardness of a concrete surface and other cementeous materials. More specifically, increasing hardness of concrete by applying a strontium based solution to its surface, and the structure made by the method. The invention also relates to application of surfactants and/or other additives in order to improve the penetration of the hardening agent into the concrete surface and other cementeous materials, improve the water and/or oil repellant properties of the concrete, and/or improve its stain resistance.

Abstract:

Disclosed are methods and solutions for sealing and curing concrete and other cementitious materials using strontium containing, non-alkali, non-silica, chemical solutions. The strontium-based solutions can be placed in admixture with cementitious materials prior to molding and curing to create a final product, or the strontium-based solutions can be applied to newly created or existing cementitious material surfaces to improve the repellent and stain, resistant properties.
