Micro-Analysis of Sulfate Salt Attack Destruction on Autoclaved-Curing Concrete
The autoclaved-curing high strength concrete was prepared with quartz powder (QP). The deterioration behavior of concrete specimens partially exposed to Na2SO4 solutions was analyzed by using scanning electron microscopy, energy dispersive spectrometer and X-ray diffraction as well. The results show that the interfacial transition zone cause the autoclaved-curing concrete damage. Sulfate chemical erosion is the main cause the damage of cement concrete. Hydration products of decomposition are the main cause of concrete crack mixing with QP. QP concrete is more susceptible to sulphate attack.
