EXPOSED REINFORCING STEEL

Exposed reinforcing steel may result from deterioration within the concrete or from errors during construction. When concrete deterioration exposes rebar, the problem usually is the result of steel corrosion, freeze-thaw damage, or both. The keys to preventing corrosion in reinforced concrete are providing adequate concrete cover depth and preventing or slowing chloride entry by using sealers or membranes or by reducing concrete permeability. Another option is changing the corrosion threshold by using a corrosion-inhibiting admixture or epoxy-coated, galvanized, or stainless reinforcing steel. To prevent freeze-thaw damage, good drainage and the proper amount of entrained air in the concrete must be provided. Air tests at the jobsite can assure that the concrete has the air content specified and ordered.
