| Abstract: | For measuring chloride diffusion coefficient of Portland cement concrete and sulphoaluminate cement -based concrete,the method of chloride migration coefficient from non-steady-state experiments is adopted. And their cement hydration products and internal structure were researched by the application of X-ray diffraction analysis(XRD) and scanning electron microscopy analysis(SEM).According to the above studies,the resistance to chloride ion erosion of sulphoaluminate cement and the resistance mechanism of t... |
