(同濟大學土木工程學院 上海 200092)[提要] 碳化混凝土的再堿化方法主要應用電滲原理，在直流電的作用下，使碳酸鈉電解質向鋼筋周圍的混凝土滲透，使鋼筋周圍混凝土再堿化。通過對+根70余年齡期的鋼筋混凝土構件所做的再堿化試驗，提出了適用于碳化混凝土再堿化維修技術的施工方法及注意事項，并提出了相關的理論，為該項技術的推廣應用奠定了基礎。
[關鍵詞] 碳化混凝土 再堿化維修The electroosmosis principle is applied on realkalization maintenance. The Na2C03 electrolyte pervades into concrete around the steel bar under the action of DC, so the concrete is realkalization. Based on a successful realkalization test on a 70 years old reinforced concrete member, the construction methods and the attentions of the carbonated concrete realkalization maintenance in situ are presented, and the realkalization theory is discussed.The foundation is set up for the widely using of the technology in our country.
Keywords: carbonated concrete; realkalization maintenance
