Abstract
The dry-wet cyclic experimental method is designed to imitate the reinforced concrete corrosion in the natural environment. The polynomial model of chloride ions transporting inside the concrete is discussed and its numerical calculation is analysed through the reasonable differencing scheme, and the stability of the differencing scheme is discussed accordingly. The chloride concentration distribution in concrete can be obtained respectively by the chemistry titration method and calculated using the above model by selecting the parameters according to the concrete material property and the stability of differencing scheme. The statistical characteristic analysis and the relativity of the calculated value and the tested value both verify the accuracy of the model.
期刊介绍：
Most of the research and experiments in the fields of science, engineering, and social studies have spent significant efforts to find rules from various complicated phenomena by observations, recorded data, logic derivations, and so on. The rules are normally summarised as concise and quantitative expressions or “models". “Identification" provides mechanisms to establish the models and “control" provides mechanisms to improve the system (represented by its model) performance. IJMIC is set up to reflect the relevant generic studies in this area.
