摘要
水工混凝土在施工过程中容易产生蜂窝、麻面、孔洞、露筋、缺棱掉角、缝隙与夹层等施工缺陷,在运行过程中又由于环境因素、化学腐蚀及交变荷载等作用的影响,出现了不断老化和多种病害现象。为保证工程的正常、安全运行,需要进行大量而复杂的修补加固。本文就混凝土缺陷和病害所采取的修补加固方法及材料进行综述。
During the construction period, hydraulic concrete trends to have defects such as honeycomb, pitted surface, holes, exposed rebar, wane edge, arris defect, surface crack and interlayer defect. In service, aging and damage occurs due to environment, chemical corrosion and alternating load. A lot of repair and strengthening measures need to be taken to ensure the regular and safe running of the project.
