中文摘要:

腐蚀电位监测、线性极化和交流阻抗测试等方法研究混凝土中添加萘系减水剂对钢筋腐蚀行为的影响.发现添加萘系减水剂的混凝土,其电阻和极化电阻大幅增加,其中以添加0.2%萘系减水剂的增幅最明显.适量的萘系减水剂有利于改善混凝土的孔隙结构,增强混凝土的密实性和抗渗透性能,从而减缓混凝土的钢筋腐蚀.

英文摘要:

The influence of naphthalene water reducer on corrosion behavior of reinforcing steel in concrete was studied by the methods of corrosion potential measurement, linear polarization and EIS test. The values of concrete resistance ( Rc ) and polarization resistance ( Rp ) of the samples with naphthalene water reducer were higher than those without naphthalene water reducer, especially in the concrete with 0.2 percent naphthalene water reducer. A suitable amount of water reducer can improve the pore structures of concrete, increase the concrete compactness and impermeability, and decrease corrosion rate of rebars in concrete.
