测试了水泥基砂浆的抗氯离子渗透性能及钢筋砂浆电极的极化电位,研究了不同阻锈剂、矿物掺合料对砂浆抗氯盐锈蚀性能的影响规律。结果表明,1.5%乙醇胺与0.5%三乙醇胺复掺,砂浆中钢筋表现出优异的抗氯盐锈蚀性能;掺入20%矿渣粉及10%粉煤灰,砂浆抗氯离子渗透性能优于其它各组;乙醇胺、三乙醇胺作复合阻锈剂,同时复掺矿渣粉、粉煤灰掺合料,复合砂浆的抗氯盐锈蚀性能最佳,且对力学性能无明显影响,适用于锈蚀混凝土结构的修复。
測試瞭水泥基砂漿的抗氯離子滲透性能及鋼觔砂漿電極的極化電位,研究瞭不同阻鏽劑、礦物摻閤料對砂漿抗氯鹽鏽蝕性能的影響規律。結果錶明,1.5%乙醇胺與0.5%三乙醇胺複摻,砂漿中鋼觔錶現齣優異的抗氯鹽鏽蝕性能;摻入20%礦渣粉及10%粉煤灰,砂漿抗氯離子滲透性能優于其它各組;乙醇胺、三乙醇胺作複閤阻鏽劑,同時複摻礦渣粉、粉煤灰摻閤料,複閤砂漿的抗氯鹽鏽蝕性能最佳,且對力學性能無明顯影響,適用于鏽蝕混凝土結構的脩複。

The mortar resistance to chlorine ion permeability and polarization potential of reinforced mortar have been measured, the influence rules of mortar chlorine salt corrosion resistance by corrosion inhibitor and mineral admixtures are researched. The results show that the rebar in mortar presents excellent chlorine salt corrosion resistance when adding 1.5% ethanolamine and 0.5% triethanolamine; mortar specimen which compound mixing 20% slag and 10% fly ash, the chlorine salt erosion resistance property is superior to specimens which mixing cement, slag and fly ash separately. Taking ethanolamine and triethanolamine as compound corrosion inhibitor, double mixing slag and fly ash, chlorine salt corrosion resistance of compound mortar turns out the best property, and has no obvious effect on mechanical property, which can apply to repairing corrosion concrete structure.
