摘要:

研究了盐碱地环境下不同配合比铁尾矿基地聚物中钢筋的锈蚀行为。通过模拟盐碱地环境对铁尾矿基地聚物-钢筋试块进行电加速锈蚀试验，利用电化学阻抗谱、腐蚀电位和极化曲线3种测试方法，研究不同配合比对试块的电化学参数和钢筋锈蚀速率的影响。结果表明：在电加速锈蚀的整个过程中，试块电阻呈现先上升后下降的趋势，表明SO $4 2 -$ 及Cl^-在腐蚀前期可以增加试块的密实度；在相同溶液浓度和电加速条件下，合理配合比有利于对钢筋的保护，延缓钢筋的锈蚀进程，陶瓷粉掺量对钢筋锈蚀规律的影响尤为明显。通过试块的阻抗(R_c)值、腐蚀电流密度(I_corr)值和腐蚀电位的变化规律表明陶瓷粉掺量较低、水玻璃模数较高、碱掺量较低、水胶比适中的配合比试块对钢筋的保护效果更好。

Abstract：

The corrosion behavior of HPB235 hot rolled round steel rebar buried in iron tailings-based geopolymers in a simulated saline-alkali environment was investigated via electrochemical impedance spectroscopy, corrosion potential and polarization curve methods, so that to clarify the influence of the formular of geopolymers on the electrochemical parameters of the test blocks and the corrosion rate of steel bar. The results show that during the corrosion process by applied electric current, the resistance of the test block increases first and then decreases, indicating that SO $4 2 -$ and Cl^- can increase the compactness of the test block. In conditions with setting solution concentration and applied electric current, the test block with reasonable formular is conducive to the protection and delays the corrosion process of steel bars. The influence of ceramic powder content on the corrosion of steel bars is particularly obvious. By comparing the evolution of the free corrosion potential, corrosion current density I_corr and impedance R_c of the steel bar with test geopolymers block of different formulars, it is found that the test block with low ceramic powder content, high sodium silicate modulus, low alkali content and moderate water binder has better protection effect for the steel bar.

Key words： saline-alkali environment geopolymers rusting of steel bars electrochemistry
