摘　　要：温福铁路处于东南沿海地区，台湾海峡西岸，许多桥梁位于海水和地下水侵蚀环境，为了确保设计使用年限达到100年以上，针对东南沿海环境温福线铁路桥梁混凝土抗腐蚀，提高耐久性，应用了CX-SUN抗侵蚀外加剂。CX．SUN海工高性能混凝土抗侵蚀外加剂产品，可解决钢筋混凝土因长期遭受地表海水和地下水中各种化学物质的侵蚀破坏而过早丧失服役现象，使混凝土使用年限提高20～30年。The Wenzhou-Fuzhou Railway lies in the southeast coast of China, west to Taiwan Strait.Many of the bridges are under conditions of the sea and underground water erosion.In order to prolong the service life of the bridge for at least 100 years,we apply for the CX-SUN anti-erosion additive so as to improve the resistance of corrosion and enhance its durability according to the environment of the southeast coast.A high-performance concrete admixture products of corrosion resistant on marine can solve the phenomenon that many reinforced concrete loss their service sO early due to a long-term exposure to varieties of chemical erosive destruction on the surface of the sea and groundwater.The addictive would prolong the service of the concrete for about 20 to 30 years.
