Study On Anti-corrsion Rust-resistance Agent Of Concreteand Its Application

China’s coastline stretches for 18000 km, the marine economy is a very important part of our national economy, therefore, marine the scale of capital construction, and all sorts of marine reinforced concrete structures as well as in saline-alkali land, industrial wastes to poor geological conditions under the huge investment, the life directly influence national sustainable development strategies. Surveys show that there have been lots of reinforced concrete structure in marine and harsh environments far below the designed lifetime is severely damaged, its loss is serious. For concrete structures by at of bad environment, analysis marine and the bad environment on concrete and the concrete in the steel of corrosion role mechanism, deepened awareness structures by marine and the bad environment corrosion bad of of(electric) chemical process and chemical Dynamics process, to concrete durability for Center, on its raw materials performance, and tie than design, and physical mechanical performance and in various marine, and bad environment in the of evolution law for integrated and system of research, summary and established concrete of seawater corrosion Dynamics theory and control theory, Developed based on "concrete anti-corrosion rust penetration agents". Through on developed of "concrete anti-corrosion resistance rust anti-infiltration agent" for multifaceted of test detection, its technology performance indicators respectively can meet RC resistance rust agent(JT/T537-2004), and concrete anti-sulfate class erosion preservatives(JC/T1011-2006), and mortar, and concrete waterproof agent(JC474-2008) and concrete plus agent(GB8076-2008) in the "efficient reduction agent" "introduction gas agent" of requirements. Therefore, in the preparation of marine and harsh environments when working with concrete, concrete with added anti-corrosion rust through in concrete impermeability agent to satisfy particular requirements for concrete and simple, reliable performance, in order to achieve concrete in different oceans or in harsh environments in different periods of performance or service life. Project will be the construction of marine concrete structures or harsh environments provide a reasonable selection of high performance concrete with materials, scientific basis, also sets the relevant national technical regulations or normative reference.
