MODEL ANALYSIS OF THE TRANSPORTATION OF CHLORIDE INTO CONCRETE EXPOURED ON DRY-WET CYCLIC CONDITION
The dry-wet cyclic experimental method is designed to imitate the reinforcedconcrete corrosion at nature environment. The polynomial model of chloride ions transportinginside the concrete is discussed and the numerical calculation of it is analyzed through thereasonable differencing scheme and the stability of the differencing scheme is discussedaccordingly. The concentration results chloride in concrete can be abtained respectively by thechemistry titration method and calculated using above model by selecting the parametersaccording to the concrete material property and the stability of differencing scheme. Thestatistical characteristic analysis and the relativity of the calculated value and the measuredvalue both verify the correction of the model.
