氯盐对受硫酸盐腐蚀混凝土性能的影响
The effect of chloride on concrete under suffate attack
摘要
Abstract
The specimens of concrete were immersed into single chloride solution, single sulfate solution and composite solution respectively; the compressive and flexural strength of concrete were tested at different immerse ages, and meanwhile the corrosion products were studied by XRD. The results indicate that the presence of chloride in composite solution can delay the damage of concrete, and the higher the concentration of chloride in composite solution, the more obvious the delayed effect. Chloride ions can react with hydration products of concrete and generate hydrated calcium aluminum chlo-ride(3CaO ? A12O3 ? CaCl2 ? 10H2O) , whose expansibility is higher than that of ettringite, becoming the reason of the delayed damage of concrete.关键词
