The method of curing reinforced concrete uses a liquid membrane-forming curing compound for the curing of reinforced concrete, but without fully coating the reinforced concrete with the curing compound, thus allowing for oxygen permeation through the reinforced concrete to effect passive layer formation on steel rebar embedded in the reinforced concrete. Prior to curing, a mask is applied to at least one surface of a slab of reinforced concrete, such that the mask covers about 10% of the surface area of the at least one surface. The at least one surface of the slab of reinforced concrete is then coated with a liquid membrane-forming curing compound. The liquid membrane-forming curing compound is allowed to dry, thus forming a curing compound layer on the at least one surface of the slab of reinforced concrete. The mask is then removed to form at least one uncoated region.
