Abstract: The influence factors to the durability of reinforced concrete structure are analyzed in this paper. Against the environmental characteristic in Chongqing, the prevention and treatment countermeasures about deterioration of reinforced concrete structure building in environment are proposed. Therefore 《ZHONGHE 2000》capillary crystalline waterproofing material will play a major role.
Key words: concrete, steel reinforcement, carbonization, corrosion, waterproofing, anticorrosion , permeable crystalline,《ZHONGHE 2000》

　　Learned that the 《ZHONGHE 2000》series waterproof materials were used in multiple-use building of Gansu provincial party committee authority. The materials were researched and developed and produced by ZHONGHE Waterproof material Co., Ltd. From a professional perspective, the author looked up 《ZHONGHE 2000》related data. The data shows that the waterproof materials were used in hundreds of civil and national defense constructions around the country and the materials have excellent effects of waterproofing and anticorrosion. Combined with the serious durability problem of constructions of our country, which we learned in the recent years, it is a worrying that the industry constructions against corrosive damages in our province, especially in the area of Lanzhou, because the environmental condition is worsening. Therefore, it is necessary to investigate the method of preventions and treatments from the start of researching the mechanism and reason of concrete structure corrosive damages. Through studying and combining with the environmental characteristic of our province, this paper is completed. Author hope it could provide analysis and reference for related personnel.
