摘要:
采用电量法和盐溶液干湿循环法对混凝土防腐涂料的抗氯离子侵蚀性能进行了试验研究; 并以电量法的通电量比和干湿循环法的18次循环时氯离子侵蚀深度为衡量指标,建议了具有一定工程适用性的混凝土防腐涂料抗氯离子保护性能的评定标准。结果表明:根据电量法的通电量比和盐溶液干湿循环法的氯离子侵蚀深度都能对混凝土防腐涂料的抗氯离子侵蚀性能做出有效评价; 干湿循环法能反映防腐涂料在试验过程中的劣化趋势,而电量法无法实现这一点; 复合型防腐涂料优于单一涂层涂料,成膜型涂料优于单一渗透型涂料。
Abstract:
The performance of anti-corrosion coating against chloride ion ingress into concrete was studied by using both ASTM C1202 and dry and wet cycling method of salt solution. Based on the electricity pass ratios of ASTM C1202 test and 18 dry and wet cycling method tests for chloride penetration depths, an applicable engineering evaluation criterion was established to classify the performance of anti-corrosion coating against chloride ion ingress into concrete. The results show that the performance of anti-corrosion coating of concrete can be evaluated by electricity pass ratios from ASTM C1202 and chloride penetration depths from dry and wet cycling method. The dry and wet cycling method can reveal the degradation trend of anti-corrosion coating, while ASTM C1202 can not. The experimental work also shows that the mixed anti-corrosion coating is more effective than single anti-corrosion coating, and the film-forming coating is better than single penetration coating.
