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.

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.
