摘要
通过回顾混凝土材料耐久性研究历史,在详细分析外界环境如盐类侵蚀、碳化作用、碱集料反应、冻融破坏以及由自身内在材料、构件、结构形式的差异对耐久性产生的不良影响基础上,总结出相应的防治方法及建议,同时提出了在多因素耦合作用下,考虑叠加影响因素的模型构建。未来对于钢筋混凝土结构层次的研究和多因素作用机理的研究将是耐久性研究的重要方向,最终有望实现钢筋混凝土工程的全生命周期设计,实现从材料、构件、结构方面的统筹考虑。
The paper reviewed the history of concrete material durability research,with detailed analysis of the external environment such as salt erosion,carbonization,alkali-aggregate reaction,freeze-thaw damage,and the adverse effects on durability caused by differences in internal materials,components,and structures the corresponding prevention methods and suggestions were summarized,and the model construction considering the superimposed influence factors under the coupling effect of multiple factors was proposed.In the future,the research on the hierarchy of reinforced concrete structures and the research on the mechanism of multi-factor action will be an important direction of durability research,and it is expected that the full life cycle design of reinforced concrete projects will eventually be realized,and the overall consideration from material、component and structure can be realized.
