Study On Corrosion Factors Of Reinforced Concrete

With the growth of reinforced concrete buildings rapidly move by the development of modern industry. However, the problem of durability of reinforced concrete is obvious as time go on, specially in some critical pollution environment. Environment influence the durability of reinforced concrete and course the inactivation of performances. The life and properties have great dangers once it happed. It is an urgent problem that how to improve the durability of reinforced concrete. The article researches diffusions of chlorine ion in reinforced concrete, carbonation and monitoring and detection of reinforcing corrosion. Reinforcing corrosion, corrosion medium and carbonation is greatly influence the durability of reinforced concrete.The article researches the principle of chloride shift in reinforced concrete by soak in saline. The result and date is similar to the real environment through this work, however, it will take a long time. This research design three different test sample: no protection; epoxide resin shield and 244 curing agent shield test sample. Measure the density of chloride ion after cut the samples which soak in saline by fit thickness. Then get the diffusion coefficient of chloride ion of each sample by the...
