摘　　要：为了研究新老混凝土粘结层之间的新型界面剂,综合改善界面剂的性能,保证其具有良好的耐抗性能,特别是抗碳化性能,通过掺加不同种类的外加剂和超细粉料,并对不同配合比的界面剂进行了抗碳化性能测试.结果表明,掺加减水剂、减缩剂和粉煤灰的新型界面剂具有很好的抗碳化性能.Pouring the new concrete directly on the carbonated concrete without removing the carbonated layer, it needs to ：research the new type of interracial adhesive between the new and old concrete. To improve the performance of interracial adhesive applied to the old concrete, the research task has been done by mixing different types of additives and uhrafine power, and ensure that it has good durability, and especially the resistance to carbonation. According to the research, the new surfactant with FDN,JM - SRA and Fly Ash has good performance of anti-carbonation. Based on the increasing section method,it needs to find a new way of repairing the diseased concrete structures.
