中文摘要:
      利用电化学快速锈蚀方法获得了混凝土中不同锈蚀程度的钢绞线,并得到了裂缝宽度与锈蚀重量损失率之间的关系。通过静拉伸试验数据的回归分析得出名义极限强度、名义弹性模量和极限延伸率的降低与锈蚀重量损失率之间的关系。
英文摘要:
      Some steel bars with different corrosion rates embedded in concrete are obtained by accelerative electrochemical corrosion method and the relation between the crack width and the corrosion loss rates of steel bars weight is achieved. On the base of extending test and multiple regression, the relations between the decreases of nominal ultimate strength, nominal elastic modulus or ultimate elongation and the corrosion loss rates of steel bars weight has been got.
