Abstract: The invention comprises a method of making a cement-based object or structure having a compressive strength greater than about 1,000 psi. The method comprises placing a cement-based material in an insulated concrete form, wherein the insulated concrete form has an R-value of at least 1.5, wherein the cement-based material comprises approximately 10% to approximately 80% by weight portland cement, and at least one of approximately 10% to approximately 90% by weight slag cement and approximately 5% to approximately 80% by weight fly ash. The invention also comprises a method of making a cement-based object or structure. The invention further comprises objects or structures made by the foregoing methods.

Abstract: The invention comprises a method of forming a concrete structure. The method comprises placing plastic concrete in a form of a desired shape, encasing the concrete in insulating material having insulating properties equivalent to at least 1 inch of expanded polystyrene and allowing the plastic concrete to at least partially cure inside the insulating material. An insulated concrete form and a method of using the insulated concrete form are also disclosed.

Abstract: The invention comprises connector for a pair of opposed spaced concrete forming panels. The connector comprises an elongate spacer member having flanges formed thereon intermediate a central portion thereof and each opposite end thereof. A portion of at least one end of the spacer member is sized and shaped to selectively engage an elongate panel bracing member. A composite insulated concrete form and a method of using the insulated concrete form are also disclosed.

Abstract: The invention comprises a foam insulating panel having an outer surface and a reinforcing member adhered to at least a portion of the outer surface of the foam insulating panel. An insulated concrete form and a method of using the insulated concrete form are also disclosed.
