The result indicates that when the air content of the concrete changes from 1 to 4 percent , the polarized resistance of the identical flow electricity time increases along with the increment of the air content , the corrosion current density reduces along with the increment of air content , the chloride ion diffusion coefficient reduces with the increment of air content ; when air content changes from 4 to 6 percent , the rule of the change of the polarized resistance and corrosion current density happens to be the opposite , the diffusion coefficient of the chloride ion increases along with the increment of air content ; when the air content is 4 percent , the rust - resisting property of concrete is best , and so is the impermeability of the concrete 试验结果表明,混凝土的含气量在1 . 9 % ~ 4 . 2 %变化时,极化电阻随含气量的增大而增大,腐蚀电流密度随含气量的增大而减小, cl -扩散系数随含气量的增大而减小;当含气量在4 . 2 % ~ 6 . 4 %变化时,极化电阻、腐蚀电流密度和cl -扩散系数的变化规律则相反;当含气量为4 . 2 %时,抗钢筋锈蚀性能最佳,抗渗性最好。 cl -扩散系数与钢筋锈蚀参数在一定程度上有着良好的相关性,抗渗性的结果较好地反映了混凝土中钢筋锈蚀的程度,可以用cl -扩散系数评价引气混凝土的抗钢筋锈蚀性能。
