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.

Treatment under mild condition with solvent of lower polarity was in favor of keeping the molecular structure and properties such as water-solubility, gelatination, etc. Acetyl groups were partially eliminated when purified by Pb2 method, leading to increased crystallinity and glass temperature, which resulted in losts of water-solubility and gelatinability. Owing to the slight oxidative degradation with H2O2 method, the changes of chain size and some functional groups of KGM molecule led to decrease of viscosity and excessive swelling rate.

采用温和条件及低极性溶剂有利於保持KGM本身的分子结构以及水溶性、凝胶性等性能；而Pb2法由於部分脱去了KGM的乙酰基，导致结晶度变大，玻璃化温度升高，最终失去水溶性和凝胶性；H2O2法则由於对KGM造成了氧化降解，也改变了分子链的大小以及部分基团，从而导致粘度降低以及溶涨速度较快。

The results show that this kind of IPN hydrogels are temperature-sensitive, and, compared with inorganically crosslinking PNIPAAm hydrogels, these IPN hydrogels exhibit enhanced storage modulus and ultrafast response rate, such as losing water of 90% within 10 min because of the porous structure which provides the water-releasing channel; by incorporation of PAAm network, the phase transition of PNIPAAm hydrogels is weakened, but the lower critical solution temperature is increased.
