以发生硼酸渗漏核电厂的钢筋混凝土结构为研究对象,通过对现场取得样品进行微观分析和宏观力学试验来研究硼酸溶液对混凝土结构的腐蚀机理和对其力学性能的影响。由现场取芯强度试验结果可知,发生腐蚀墙体区域取得芯样的抗压强度值低于未腐蚀区域的芯样试验强度,这表明硼酸溶液会影响混凝土材料的耐久性能。
Taking the borosilicate leakage nuclear power plant’s reinforced concrete structure as the research object, the corrosion mechanism of the boric acid solution on the concrete structure and the influence on the mechanical properties of the concrete structure were studied by microscopic analysis and macroscopic mechanical test on the samples obtained in the field. According to the coring strength test results in the field, the compressive strength value of the core sample in the area where corrosion occurs is lower than the core sample strength in the non-corroded area, which indicates that the boric acid solution will affect the durability performance of the concrete material.
