Based on the short gel-time features of ordinary cement sodium-silicate and alkali-activated salic cementitious materials, an ideal structure model of high performance sodium-silicate suspension two-shot grouting material was established. An experiment was undertaken to verify the solidification value of Na~+ and water-erosion resistance of a grouting material combined with cement and metakaolin-sodium silicate. This paper put forward a compact structure with a dominant ingredient of-Si-Al-H zeolite gel formed on later age and a minor part of C-S-H formed on early age, which composed of sodium-silicate, substances that could release Ca~(2+) spontaneously and stably or by the aid of sodium-silicate, and active salic substances.

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，本文建立了高性能水玻璃悬浊型双液灌浆材料的理想结构模型，并通过水泥复合偏高岭土-水玻璃灌浆材料的Na~+固化性能和抗水溶蚀性能进行了试验验证，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，其组成要素为水玻璃、能自发稳定地或在水玻璃作用下迅速释放出Ca~(2+)的物质、活性硅铝质材料。
