Improving Performance of Concrete Structures
Corrosion of steel reinforced concrete affects everyone, leading to expensive repairs and intensive maintenance programs. Budgeting of repairs and maintenance programs becomes difficult when structures do not meet their intended life cycle requirements. Corrosion of reinforcing steel in concrete structures leads to concrete failure, impacting the public with delays and detours. The Federal Highway Administration’s National Bridge Inventory records reflect that less than 16% of existing U.S. bridge decks utilize corrosion resistant reinforcing steel. Beyond bridge decks and highway infrastructure, corrosion protection of concrete reinforcement is an even smaller percentage. Preservation of assets by using zinc-coated reinforcing steel can be a cost-effective solution to improving the life cycle and durability of concrete structures.
