摘　　要：耐久性研究是目前混凝土材料性能研究的热点方向之一,目前各科研机构多采用各类仪器设备对工程中常用的构件进行抗渗透、冻融、碳化和各类盐类侵蚀测试与分析,对于此类研究国内外已取得了不少成果。从耐久性测试分析入手,对影响混凝土运营的各种外部环境侵蚀指标进行阐述分析,综述当前研究进展,并对测试混凝土耐久性的各项设备和方案设计进行分析,对后期相关设备研究提供参考帮助。The durability research based on beam and slab components is one of the hot research directions of concrete materialperformance at present.At present,various scientific research institutions mostly use various kinds of instruments and equipment totest and analyze the anti permeability,freeze-thaw,carbonation and various salt erosion of the commonly used components in theproject.Many achievements have been made in this kind of research at home and abroad.However,limited to the current domesticresearch situation,it is difficult to study the durability of concrete components by widely using various carbonation boxes,freeze-thaw testing machines and permeameters.In view of the above problems,this paper starts with the analysis of the current durabilityresearch indicators,summarizes and discusses the existing various types of instruments and equipment,and further carries out theoptimization and improvement design analysis,providing reference for the later research of related equipment.
