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.
