Silicon-aluminum-based rapid curing material for high-water-content soft soil and preparation method of silicon-aluminum-based rapid curing material

The invention relates to a silicon-aluminum-based rapid curing material for high-water-content soft soil and a preparation method of the silicon-aluminum-based rapid curing material. The silicon-aluminum-based rapid curing material comprises the following components in parts by weight: 16-18 parts of sand washing filter cakes, 2-4 parts of walnut shells, 3-6 parts of metakaolin, 1-2 parts of calcium oxide, 0.5-1 part of silica fume, 0.4-0.8 part of sodium silicate and 0.1-0.2 part of sodium hydroxide. Soft soil with high water content and even soft soil with the water content larger than the liquid limit can be directly cured, and the cured soft soil meets the road use requirement. 本发明涉及一种高含水软土的硅铝基快速固化材料及其制备方法。所述硅铝基快速固化材料按重量份包括：洗砂滤饼16-18份，核桃壳2-4份，偏高岭土3-6份，氧化钙1-2份，硅灰0.5-1份，硅酸钠0.4-0.8份，氢氧化钠0.1-0.2份。本发明可以直接固化高含水率的软土，甚至是含水率大于液限的软土，固化后满足道路使用要求。
