【摘要】 本文应用交流阻抗谱方法研究了混凝土的抗渗性和氯离子扩散性。通过对掺粉煤灰混凝土和基准混凝土的性能对比表明 :掺粉煤灰混凝土的氢氧离子扩散系数和氯离子扩散系数均小于基准混凝土 ;在长期海水侵蚀下 ,掺粉煤灰混凝土的氢氧离子扩散系数的氯离子扩散系数亦均远小于基准混凝土。更多还原

【Abstract】 In this paper,impermeability and chlorion diffusion of concrete are measured by way of AC impedance spectroscopy.Based on the contrast between fly ash concrete and standard concrete,it is found that the hydroxide ion diffusion coefficient and the chlorion diffusion coeffcient of fly ash concrete are smaller than that of standard concrete.On the condition of long time seawater corrosion,the hydroxide ion diffusion coefficient and the chlorion diffusion coefficient of fly ash concrete are far smaller than that of standard concrete. 〔更多还原
