涂层对应力腐蚀条件下混凝土氯离子渗透性的影响

涂层混凝土在应力腐蚀条件下氯离子渗透性能的变化是一个新的课题。本文利用自行设计的加载设备对混凝土保护涂层及涂层涂刷次数等不同情况下的氯离子渗透性进行了研究。研究表明，保护涂层减小了混凝土在应力腐蚀环境作用下抗弯强度的损失。同时也提高了混凝土的抗氯离子渗透性，而且随着保护涂层刷涂次数的增加这种优越性越明显。

Influence of coating on perrneablity of concrete chloride ion in condition of stress corrosion

In the condition of stress corrosion, the change of permeability to coating concrete chloride ion is a new project. Through using the self-designed loading device, the permeability of coating concrete chloride ion with concrete protective coating and different brush coating times hos been researched in this paper. Research results show that, protective coatings decrease the loss of bending strength by the action of stress corrosion, at the same time improve the resistance of chloride diffusion. And the superiority shows obvious with the brush coating time accretion of coating.
