清水混凝土防护材料优选研究

Selection Research of Protective Material for As-cast Finish Concrete

该文基于对混凝土外观质量的影响对防护材料进行了优选,并采用电通量评价了防护材料的防护效果,结果表明:环氧树脂材料防护涂抹后,混凝土外观清晰度增加,各有色物质显色深度增加;氟碳漆防护涂抹后,混凝土表面一直呈乳白色,与混凝土初始外观相差很大;硅烷使用之后,混凝土试件外观基本无变化;水泥基防水灰浆施工之后的表面形态,看起来与普通砂浆区别不大;对于抗氯离子渗透性能而言,丙烯酸酯和氟碳漆防护效果非常明显,但环氧树脂和硅烷的防护效果较差。

In this article,we select protective materials and evaluate protective effect by adopting electric flux in the light of effect on quality of concrete appearance.The results show that：concrete looks much clearer,and color depth of colored materials increases after epoxy resin protective material is applied;surface of concrete is always milk white,which is very different from initial appearance after fluorocarbon paint is applied;after the use of silane,appearance of concrete sample is basically unchanged;the surface does not seem to be very different from that of ordinary mortar after construction of cement-based waterproof mortar;in terms of performance of concrete against chloride ion permeation,the protective effect of acrylate and fluorocarbon paint is obvious,but that of epoxy resin and silane is less effective.
