摘要
利用不同含量聚合物的水泥基涂层对同一强度的混凝土进行表面防护,研究防护前后混凝土的吸水性能、抗氯离子渗透性能和抗硫酸盐腐蚀性能的变化。通过实验探究发现:相比较于未涂敷保护层的混凝土,掺加不同含量聚合物的水泥基涂层可以显著提高混凝土的耐久性能;并且随着涂层中聚合物含量的增加,混凝土的吸水性能和抗氯离子渗透性能增强,而抗硫酸盐干湿循环腐蚀性能有微弱的降低。
The surface of the same strength concrete was treated by coating polymer modified cement-based coatings containing different proportions EVA polymer.The water absorption performance,chloride ion penetration resistance and sulfate corrosion resistance of concrete before and after protection were studied.Through experimental research,it is found that polymer modified cement-based coating containing different contents polymer can significantly improve the durability of concrete compared with concrete without protective layer.Moreover,with the increase of polymer content in the coating,the water absorption of concrete and the resistance to chloride ion penetration are enhanced,while the resistance to sulfate corrosion is slightly reduced.
