【摘要】 对停、缓建工程的混凝土钢筋预留部位及进场钢材若不及时采取有效的防护措施 ,将使裸露钢筋因自然环境尤其是冻融而遭受腐蚀 ,减小截面并降低混凝土对钢筋的握裹力 ,还会使混凝土产生裂缝 ,降低结构整体寿命。采取有效的措施对钢筋混凝土进行保护 ,实践表明效果较好。更多还原

【Abstract】 If the preset parts of reinforced concrete and steel in field were not protected by effective measures in the stopped or postponed projects, the exposed reinforcing bar will be destroyed in natural surroundings, especially under the freeze thaw action The section decrease will reduce the grip strength of concrete, cause concrete cracking and thus result in the reduction of working life of the whole structure Specific methods to prevent reinforced concrete from corrosion are introduced and effectiveness has been proven更多还原
