| 摘 要： | 钢筋锈蚀是造成混凝土结构耐久性劣化的原因之一,文中采用线性极化法,通过外加电流加速混凝土中钢筋锈蚀,主要研究掺合料对混凝土钢筋锈蚀的影响,结果表明:混凝土抗钢筋锈蚀性能与抗氯离子渗透性具有一致性,以15%的矿渣和15%的粉煤灰混掺作为矿物掺合料时混凝土抗钢筋锈蚀性能最好。

| Abstract: | The reinforcement corrosion is one of the reasons that result in the degeneration of concrete durability. In this paper, we prepared reinforcement concrete with different mineral admixtures. Under accelerating corrosion method of external current, we studied the effect of mineral admixture on the reinforcement corrosion by the chemical parameters tested by linear polarization method.The result shows that the property of reinforcement corrosion corrosion is consistent with function of resitance to chloride ion penetration, performance is the best with 15% slag and 15% fly ash as the mixing mineral admixture. |
