【摘要】 试验研究了钢筋直径、混凝土强度等级、保护层厚度、腐蚀电流、钢筋位置和钢筋类型等因素影响下钢筋混凝土锈胀裂缝扩展规律。结果表明,锈胀裂缝随时间呈线性增大趋势,通过对试验数据的分析提出了锈胀裂缝宽度预测的经验公式。更多还原

【Abstract】 The rule of corrosive crack expansion of reinforced concrete with the influence of bar diameter,concrete strength grade,protective layer thickness,corrosion current,reinforcing bar location and type is studied through test.The result shows that corrosive crack takes on linear increase trend with time.Through analysis on test data,this paper puts forward the empirical formula of corrosive crack width prediction.更多还原
