钢筋混凝土结构物的防腐技术（Anticorrosion technology of reinforced concrete structure）

钢筋混凝土结构物的防腐技术（Anticorrosion technology of reinforced concrete structure） Abstract: in this paper, the reinforced concrete anticorrosive technology and preventive measures, and the concrete in Cl to determine the content of quantitative indicators, through the test of 7 kinds of concrete admixture can slow down the corrosion rate of steel chloride, emphasizes to set up the quality standard of technology about ice snowmelt, agent and test procedures. 1, steel in chloride environment corrosion technology and preventive measures 1.1 anti corrosion technology Study on anticorrosion technology, is put into operation from the structure, internal corrosion initiation time as close as possible design life. To completely avoid the corrosion of Cl, the most effective method is a fundamental guarantee of the concrete and the chloride environment is isolated, in fact this is not possible. It is important how to effectively control the total amount of chloride, which is defined in the specified range. According to the research results and the corrosion mechanism of the electrochemical behavior of steel in chloride environment, generally can effectively prevent concrete pH and ensure the passivation film on the interface of steel not activation, maintain constant potential, electrical double layer to avoid the steel surface depolarization occurs, we can effectively control the corrosion. The anticorrosion technology. In this paper, anticorrosion technology is summarized as follows: (1) the total amount of Cl - limited value in concrete The so-called limit means the maximum allowed value in concrete. The research shows that the total Cl limit should be less than 0.18% (ordinary cement concrete weight percentage), equivalent to 0.55kg / m3, the value of the equivalent of the United States (ACI) limit, 8% lower than the standard value of the Japanese Society of civil engineering, the research results with the United States and Japan developed countries based on the standard value is
