本文初步建立了模拟海洋大气环境作用下混凝土耐久性的加速试验方法,并采用10倍水溶解钢筋周围混凝土粉末的方法制取混凝土孔溶液,研究了在氯离子侵蚀和碳化共同作用下使钢筋锈蚀的游离氯离子与氢氧根离子的含量的变化。并对不同水胶比的普通混凝土与掺工业废渣混凝土损伤失效过程进行了试验研究,根据试验结果建立了基于[Cl-]和[OH-]浓度的钢筋锈蚀临界状态方程,研究结果对海洋大气环境下盐雾和碳化共同作用的混凝土的使用寿命预测和耐久性设计具有参考意义。 In this paper, an accelerated test method for simulating the durability of concrete under the influence of the marine atmospheric environment was initially established. The concrete pore solution was prepared by dissolving the concrete powder around the steel bar with 10 times of water. The effects of chloride ion erosion and carbonation The change of free chlorine ion and hydroxide ion content. The damage and failure process of ordinary concrete mixed with industrial waste concrete with different water cement ratios was studied. Based on the experimental results, the critical state equations of corrosion of reinforced concrete based on [Cl-] and [OH-] concentrations were established. Environmental salt spray and carbonization of the role of concrete life prediction and durability design of reference.
