Metal-cement based concretes and methods for making same

A method of manufacturing a concrete product, comprising:

• providing a metal-based cementing agent comprising at least one of Fe2O3, Fe3O4, and zinc oxide, the metal-based cementing agent being provided in a granular form having a mean diameter of less than 100 microns, the metal-based cementing agent comprising between 5 and 20% by weight of a total mass of the concrete product;
• providing a cement reacting agent comprising phosphoric acid in an aqueous concentration of between 75 and 93%, the cement reacting agent comprising between 5 and 15% by weight of the total mass of the concrete product;
• providing an aggregate comprising at least one metallic oxide, the aggregate being provided in a size range of 80% by weight between 100 microns and 2 millimeters, the aggregate comprising between 40 and 80% by weight of the total mass of the concrete product;
• providing a setting agent comprising at least one of Fe+2 and Mn+2, the setting agent being provided in a granular form having a mean diameter of less than 100 microns, the setting agent comprising between 2.5 and 10% by weight of the total mass of the concrete product;
• providing an acid scavenging agent comprising at least one of K-feldspar and magnesium silicate, the acid scavenging agent being provided in a granular form having a mean diameter of less than 50 microns, the acid scavenging agent comprising between 0.5 and 3% by weight of the total mass of the concrete product;
• 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;
• placing the liquid concrete mixture in a form and allowing the liquid concrete mixture to set up and cure into the concrete product.
