Abstract This research concerned the corrosion behaviour of low-carbon steel reinforcements in Portland cement, alkali-activated slag, and alkali-activated slag-steel slag mortars under simulated marine environment. Electrochemical measurements were used to monitor the corrosion process. The results showed that the steel reinforcements in alkali-activated mortars showed higher corrosion resistance under simulated submerged zones than that in Portland cement mortars. However, alkali-activated mortars presented higher deformation and more cracks, resulting in severe corrosion under simulated tidal zones. The incorporation of steel slag reduced the deformation, changed chemical compositions of the pore solutions, and therefore increased the corrosion resistance of the steel reinforcements.

模拟海洋环境下低碳钢筋在碱活化渣钢渣和硅酸盐水泥基砂浆中的腐蚀行为

摘要 本研究涉及在模拟海洋环境下波特兰水泥、碱活化矿渣和碱活化矿渣钢矿渣砂浆中低碳钢筋的腐蚀行为。电化学测量用于监测腐蚀过程。结果表明，碱活化砂浆中的钢筋在模拟淹没区下的耐腐蚀性能高于硅酸盐水泥砂浆。然而，碱活化砂浆变形较大，裂缝较多，在模拟潮汐带下腐蚀严重。钢渣的加入减少了变形，改变了孔溶液的化学成分，从而提高了钢筋的耐腐蚀性能。
