摘　　要：碱集料反应是影响混凝土结构耐久性能的重要因素之一。通过系列对比试验，进行了自修复渗透结晶型防水材料在不同材料用量、高活性集料含量、碱掺量、碱溶液等条件下对混凝土碱集料反应的影响研究，并进行了反应机理探讨。结果表明：自修复渗透结晶型防水材料通过化学转换作用提高了混凝土的整体抗渗性能，对混凝土碱集料的反应具有良好的抑制效果。Alkali-aggregate reaction is one of the important tures. Through factors that influence the durability of concrete struc- a series of contrast tests, the research on the impact of self-repairing capillary crystalline waterproof- ing materials on Alkali-aggregate reaction was carried out under different conditions, such as different material con- sumption, highly-active aggregate content, alkali content, and different alkali solutions and the reaction mechanism was discussed. The results show that the self-repairing capillary crystalline waterproofing materials improve the anti- permeability of concrete through chemical transformation and it has good effects on the inhibition of concrete alkali- aggregate reaction.
