Metal-Cement Based Concretes and Methods for Making Same
A method of manufacturing a concrete product includes providing a metal-based cementing agent including at least one of Fe2O3 and Fe3O4, an aqueous phosphoric acid cement reacting agent, an aggregate having at least one metallic oxide, a setting agent including at least one of Fe+2 and Mn+2, and an acid scavenging agent including at least one of K-feldspar and magnesium silicate. The method includes mixing the metal-based cementing agent, the cement reacting agent, the aggregate, the setting agent and the acid scavenging agent together to form a liquid concrete mixture, and placing the liquid concrete mixture in a form and allowing the liquid concrete mixture to set up and cure into the concrete product. The method can optionally include the additional step of placing the concrete product into an oven at a temperature of between 170 and 190 C.
