過去的研究中多著重於探討氯離子於混凝土中的擴散行為，卻未深入探討氯離子擴散與鋼筋腐蝕間的交互關係，氯離子擴散公式中亦未考慮鋼筋腐蝕因子，因此本研究探討砂漿試體中氯離子擴散行為與鋼筋腐蝕程度之相關性。研究中透過通電方式製作腐蝕程度不同的鋼筋後，再以淡水或鹽水作為拌合水製作水灰比0.6之內埋鋼筋砂漿試體，再置於不同養護環境中，以觀察氯離子濃度分布與鋼筋腐蝕之相對關係。試驗結果顯示，氯離子的分佈可能受鋼筋腐蝕影響。水化早期(7天)時，於淡水拌合、鹽水養護之環境下，氯離子受鋼筋腐蝕吸引，氯離子濃度隨鋼筋初始通電時間增加，上升幅度約有3倍之多，而無論鹽水拌合、不拆模靜置於大氣中或於飽和石灰水養護之環境，鋼筋腐蝕的過程中卻排斥氯離子，濃度下降幅度約為17%~43%。然而，就長期水化(28天)而言，該影響較不顯著，很可能緣於水化漿體限制氯離子的移動。另外，本研究中亦透過碳化後之試體觀察氯離子與鋼筋腐蝕相互影響關係。當碳化深度不足以影響鋼筋時，隨著碳化深度增加，因氯離子不易進入試體內部，鋼筋腐蝕速率亦趨緩。

This study explored the relationship between the diffusion of the chloride ions and the reinforcement corrosion in mortar. Such relationship was not studied in literature although the diffusion of chloride ions in concrete was well discussed. In this study, the corroded reinforcements were prepared in advance by applied currents. Mortar specimens with w/c of 0.6 were prepared and cured using either salt or fresh water. Results showed that the chloride ion distribution was associated with the reinforcement corrosion. During the early hydration, the chloride ions were attracted by the reinfoecement corrosion in the specimens prepared with salt water and cured in fresh water. On the contrary, the chloride ions were repulsed in those prepared with salt water and cured either in air or by self-curing. However, in the long-term hydration, such influencing effects were not clear, possibly due to the hydration. In addition, this study explores the above relationship in carbonated mortar. As the carbonation proceeded, the chloride ion migration slowed down and the reinforcement corrosion was reduced.
