摘要
为寻找碳化混凝土的处理方法、防止混凝土碳化,总结了影响混凝土碳化的因素及其对混凝土碳化的影响,介绍了国内外学者提出的碳化预测模型.发现了导致钢筋表面的钝化膜破坏以致钢筋锈蚀,是造成混凝土结构耐久性劣化、影响混凝土结构寿命的重要因素.提出了对碳化混凝土的处理方法和防止混凝土碳化的措施.
In order to find the disposal ways of carbonized concrete,the factors which influence the concrete carbonation and its influence on concrete carbonation are summed up,and the carbonation forecasting models proposed by domestic and foreign experts are introduced.The results show that,the damage of the passive film on the concrete iron surface leading to erosion is the key factor which causes the endurance degradation and influences the quality period of concrete structure.Further,the disposal methods of carbonized concrete and the measures of preventing concrete carbonation are put forword.
