ABSTRACT:
A surface seeded exposed particulate concrete method of use includes use of small particulates, the particulates not necessarily chemically inert in the concrete mixture. The particulates are broadcast over the upper surface of the concrete, and mixed into the cement paste derived from the concrete matrix by floats and finished by hand sponging. A surface retarder and vapor barrier are applied, and washing and curing operations follow. The present invention adds a chemical treatment of hydrolyzed alkali silica solution, preferably lithium quartz, penetrating the upper surface of the concrete mixture with minerals and silicates within the concrete mix. The resultant exposed particulate concrete has extreme flatness and high wear resistance suitable for high-traffic flooring applications, aesthetics resembling terrazzo or ceramic tile at a fraction of the price, and the strength and resistance to corrosion expected of concrete surfaces.
