本文根据西宁市一例粘土砖内硫酸盐对现浇钢筋混凝土结构的化学腐蚀破坏事例 ,用XRD法分析了腐蚀产物 ,结果表明 :梁圈混凝土的腐蚀属硫铝酸钙 石膏 碳化型综合腐蚀 ,基础地板混凝土的腐蚀属硫铝酸钙型腐蚀。
In this paper, a case of chemical corrosion of cast-in-place reinforced concrete with sulfate in clay bricks in Xining City was analyzed. The corrosion products were analyzed by XRD. The results showed that the corrosion of the concrete with annular girder was due to the comprehensive corrosion of calcium sulfoaluminate gypsum Floor corrosion of concrete is calcium sulfoaluminate corrosion.
