Experimental Study of Sulfate Attack Resistance Performance on Cement Concrete Pavement

Airport concrete pavement in high latitude northwest area attacked by sulfate of different extent, which influence early strength and ultimate strength of cement concrete. In this paper, the double doped silica fume and fly ash concrete have been made long-term immersion test research. From the mass loss rate, compressive strength and flexural strength, effect on the corrosion resistance are studied with fly ash, silicon ash adding in a composite Portland cement. Methods to improve the performance of sulfate attack resistance are obtained by experiment.
