The application of reinforced concrete. The use of stainless steel ribs in reinforced concrete structures is used to increase the strength and resistance to harsh marine environments and the formation of chlorides in concrete. Corrosion of embedded steel bars, corrosion-resistant stainless steel concrete on the deck of many marine structures (eg, the United States Coosbay Bridge meets requirements for strength corrosion and earthquake resistance, maintenance-free service life up to 120 years), piers, piers, pile foundations, breakwaters, mooring systems, rigs, gangways, railings, also in the chemical industry and others The infrastructure of important process equipment with high corrosion resistance requirements is used. In urban infrastructures such as the overpass in New Jersey, USA, stainless steel tendon concrete structures are also used. Compared with ordinary carbon steel reinforcements, the upfront cost of stainless steel tendons is higher. However, considering its good comprehensive performance and service life, it is still cost-effective.
