摘要
钢筋混凝土是世界上应用范围最广的建筑材料之一。目前有大量的钢筋混凝土结构遭到由钢筋锈蚀导致的破坏,使其服务寿命低于设计值或预期值。近年国外(主要是英国)用于修补和修复由钢筋锈蚀破坏的建筑结构的技术方法包括常规的打补丁修补和涂层修补方法、阴极保护、电化学氯化物萃取(电化学除盐)、再碱化和使用阻锈剂等。
Reinforced concrete is one of building materials most widely used in the world.Nowadays a great num ber of reinforced con crete structures suffered from the damage caused by corrosion of rebar,which may short-en the service life of the structure.Renew and remedy techniques for building structure suffering rebar corro sion,which were developed abroad(mainly in Britain)in recent years,include patching method,coating remedy method,cathodic protection,electrochemical chloride extraction,realkalization and steel bar corrosion inhibitors.
