【摘要】 应用交流阻抗谱方法对钢筋表面有机涂层的抗渗性进行了研究.结果表明,有机涂层的不同抗渗性会引起不同的阻抗谱响应,因此可用其作为灵敏的检测方法.有机涂层在浸泡3~7 d后,由于抗渗性的不同,在低频区其相角有明显变化,抗渗性较差的样品相角明显变小,电容显著增大.更多还原

【Abstract】 The anti-permeability of organic coating on rebar was studied by means of AC impedance technique.The different anti-permeability of different coating gives rise to different response of impedance spectroscopy.This may be applied as a sensitive measure for the anti-permeability.After 3～7 d immersion in water,phase angle at low frequency changes significantly due to difference in anti-permeability.更多还原
