摘　　要：钢纤维混凝土的腐蚀,严重影响了建筑结构的使用寿命和耐久性,特别在沿海地区犹为明显。本文在研究钢纤维混凝土腐蚀机理的基础上,制作了钢纤维混凝土试块。通过对涂有不同防腐材料的钢纤维混凝土试块做中性盐雾试验、紫外线试验、氙灯老化试验,研究了不同涂层的防腐效果。研究结果表明:环氧树脂+氟碳树脂、渗透结晶材料的防腐效果最好,可以大幅度提高沿海地区工业、民用和国防设施的耐久性。The corrosion of steel fiber reinforced concrete seriously affects the life and the durability of the steel fiber reinforced concrete particularly in coastal areas.On the basis of the corrosion mechanism of steel fiber reinforced concrete,the steel fiber concrete block was produced.The neutral salt spray test,UV test,xenon lamp aging test were done for the different anticorrosion materials of steel fiber reinforced concrete block.The anticorrosion ability with different coating materials was studied.The results show that anticorrosion ability of epoxy fluorocarbon resin and capillary crystalline materials is the best which can greatly improve the durability of the coastal areas of industrial,civil and defense facilities.
