浅谈如何提高混凝土的耐硫酸盐腐蚀性

Discussion on How to Improve the Sulfate Corrosion Resistance of Concrete

研究目的:我国的西北、西南和沿海的许多地区地下都富含其溶解有硫酸盐的水,对混凝土都有侵蚀性。所以,探讨如何提高混凝土的耐硫酸盐腐蚀性的问题,对提高工程质量和其寿命有着十分重要的现实意义。研究结论:在工程施工中,采取在混凝土中掺WQ系列的防腐剂或SRA型钢筋混凝土防腐剂,以及采取其他相关措施,提高混凝土耐硫酸盐的腐蚀性能,取得了良好的效果。可以在高硫酸盐地区推广使用WQ系列防腐剂或SRA型钢筋混凝土防腐剂,提高混凝土工程耐侵蚀性和工程质量。

Research purposes： In many areas of northwest, southwest and coastal region in China, underground water riches in sulfate which erodes concrete. So, discussing on how to improve the sulfate corrosion resistance of concrete is of great practical significance to improve engineering quality and lifetime. Research conclusions： In construction, impregnation with WQ serial or SRA type concrete corrosion- prevention combining with other measures can improve the sulfate corrosion resistance of concrete. Therefore, WQ serial or SRA type concrete corrosion - prevention can be spread and applied in sulfate - rich areas to improve the sulfate corrosion resistance and quality of concrete.
