This invention relates to a reinforced concrete structure of enhanced corrosion resistance. The invention structure finds particular utility in service in brackish or saline water. The reinforced concrete of the structure is, on its surface, in contact with a low resistivity grout. Anode elements are in contact with the grout, such as at the surface of the reinforced concrete or by partial or full embedment in the grout. Together with this combination, a high resistivity material is provided as a covering over the low resistivity grout and anode elements. The resulting structure is especially useful when in contact with seawater, and most particularly seawater subject to tidal action.

A steel reinforced concrete structure adapted for contact with conductive liquid, and particularly for contact with saline water subject to variations in level, said variations thereby creating a high corrosion zone for steel reinforced concrete that comes in and out of liquid contact, said structure comprising: an anode assembly adjacent to the surface of said reinforced concrete and located at least in part along said high corrosion zone; a grout in contact with said anode assembly as well as in contact with said reinforced concrete, said grout having a low specific resistivity; and an air porous concrete covering over said grout, said concrete covering having a high specific resistivity.
