为提高混凝土结构的耐久性及进一步推广应用水性渗透型防水剂,通过对混凝土进行渗水性、抗盐冻剥蚀、耐磨性、抗裂性与碳化试验,研究了水性渗透型防水剂的应用效果,解释了其作用机理。试验结果表明:水性渗透型防水剂生成的特征凝胶物能够填充混凝土的空隙与微裂缝,有效地改善混凝土的密实性,显著地提高混凝土的耐久性,在潮湿环境中使用效果更佳。
In order to improve the durability of concrete structure and further promote the application of water-based permeable water-repellent agent, the application effect of water-based permeable water-repellent agent was studied through water-permeability, anti-freezing and denudation, abrasion resistance, , Explains its mechanism of action. The experimental results show that the characteristic gels formed by water-based permeable waterproofing agent can fill the gaps and micro-cracks of concrete, effectively improve the compactness of concrete, significantly improve the durability of concrete and better effect in wet environment.
