The study on the hardening mechanism of the soft soil with the materials shows that the hardening procedure can be divided into three stages:(1). Hydrating and dissolving stage, when material A and material B of the high-water-content and quick-setting materials respectively dissolve and balance in water.(2). Gel and consolidating stage, when the materials hydrate into calcium crystal and the ion exchange and aggregation of soil particles occur in an alkaline environment.(3). the structure developing stage, when the calcium crystals connect each other, absorb and crystallize the water around; the hydrate remnants, calcium hydroxide, carbonate continuously in water and in the air.

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.

Methods Porcine bile duct and ureter were treated using detergent sodium dodecylsulphate and 1% Triton X-100 to prepare the acellular lumens matrix. The toxic effects of different concentrations of acellular lumens matrix extract were tested by MTT to assess the proliferation of human scarfskin fibroblasts. The cytotoxicity of the target biomaterial was graded according to the national standards. The growth manner of the human intrahepatic bile duct endothelial cells seeded on the acellular lumens matrix was studied after 20 d under scanning electron microscopy.
