Erials, such as instable geltime, low stability, poor underwatererosion resistance and so on, and based on the short geltime features of ordinary cement sodium silicate and alkaliactivated salic cementitious materials, an ideal structure model of high performance sodium silicate suspension twoshot groutingmaterial is established. An experiment is undertaken to verify the solidification value of Na+ and watererosion resistance of a grouting material combined with cement and metakaolinsodium silicate. This paper puts forward a compact structure with a dominant ingredient of—Si—Al—H zeolite gel and a minor part of C—S—H by means of IR and SEM microanalysis method.

摘要］ 针对隧道注浆工程用普通水泥水玻璃双液注浆材料存在凝胶时间不稳定、产物稳定性和抗地下水侵蚀性能差等主要问题，结合普通水泥水玻璃快速胶凝和碱激发硅铝质胶凝材料的特点，建立了高性能水玻璃悬浊型双液注浆材料的理想结构模型，并通过水泥复合偏高岭土水玻璃注浆材料的Na+固化性能和抗水溶蚀性能进行了试验验证，结合IR和SEM微观测试分析手段提出其组成结构应是以—Si—Al—H类沸石凝胶物质为主、C—S—H为辅的复合共存密实结构。
