摘　　要：与普通混凝土相比,碱激发混凝土护筋性能以及抗侵蚀、抗冻性能良好,被视作21世纪发展潜力最好的建筑结构材料,在桥梁等建筑工程中有良好应用,但与普通混凝土相同,碱激发混凝土也存在钢筋锈蚀的问题,氯离子侵蚀是最主要的原因。文章对氯离子锈蚀碱激发混凝土内钢筋的相关问题进行综述,把握氯离子对混凝土钢筋的锈蚀机理,总结氯离子对碱激发混凝土钢筋锈蚀的影响,并归纳碱激发混凝土的抗氯离子锈蚀性能,简单展望碱激发混凝土今后研究的相关方向。Compared with ordinary cement concrete,alkali activated concrete has such good properties of steel reinforcement protection,high corrosion resistance and forst resistance,it is regarded as the most potential building material in the 21 st century,and has a good application in constructional engineering such as bridge construction.While,alkali activated concrete also has the problem of reinforcement corrosion,it is in one tale with ordinary cement concrete,the most important reason is chloride penetration.Related issues that chloridion corrosion reinforcement in alkali activated concrete were summarized in this paper,the corrosion mechanism from chloridion to concrete reinforcement was grasped,the influence of alkali activated concrete reinforcement corrosion from chloridion was summarized,at the same time,the chloride pentration resistance of alkali activated concrete was generalized.At last,alkali activated concretes’research direction in future was expected simply in the paper.
