Chloride ion erosion experiment considering loads

The bending beam to simulate the load of 0.2 0.4 stress ratio and 5% NaCl solution jointly function proceed chlorine ion erosion test. Test results show that the same depth of chlorine ion with the increase of soaking time and stress level increases, except the concrete surface layer. Introducing chloride diffusion coefficient of degradation effects, considering the effect of load is established with the coefficient of load, based on the consideration of the load, chloride ion erosion models with experimental results verify the new model and the contrast experiment measured data fitting high quality.
