Preparation method of nano soil stabilizer
The invention discloses a preparation method of a novel nano soil stabilizer, which comprises the following steps of: fully mixing raw materials of nano silicon dioxide, a cementing material, a basic catalyst, a surfactant and slag or a slag mixture according to a formula ratio, grinding until the Blaine specific surface area is 0.35-0.4 m < 2 >/g, drying until the water content of the mixture is less than 2%, and sieving by a 80-micron square hole sieve to obtain the novel nano soil stabilizer. And the finished product fineness and SO3 content are inspected to be qualified to obtain the product. The nano soil stabilizer prepared by the preparation method is super-strong cement, and can react with various soils to form a stable and durable forming component in vast areas without sand and gravel materials. The nano soil stabilizer has the properties of pressure resistance, seepage resistance, freezing resistance and the like after being mixed and rolled with soil according to a certain proportion and extruded and compacted, has the characteristics of high consolidation strength, good water stability, small deformation, high durability, wide application range and the like, and can be widely applied to water conservancy and hydropower engineering, agricultural water and soil engineering, road traffic engineering, foundation engineering, water conservancy and hydropower engineering and the like. Clay, waste residue products and the like are produced.
本发明公开了一种新型纳米土壤固化剂的制备方法，将配方量的原料纳米二氧化硅、胶凝材料、碱性催化剂、表面活性剂、矿渣或矿渣混合物充分混合后，粉磨至勃氏比表面积0.35‑0.4m2/g，烘干，使得混合物的含水量小于2％，然后过80微米方孔筛，经成品细度、SO3含量检验合格，即可得出。按该制备方法制得的纳米土壤固化剂，既是一种超强水泥，更能在广大无砂石料地区，与各类土壤发生反应成为稳固持久的成形构件。采用该纳米土壤固化剂通过按一定比例与土壤拌和碾压，挤压密实后具有抗压、防渗、抗冻等性能，其固结强度高、水稳性好、变形小、耐久高及适用范围广等特点，可广泛应用于水利水电工程、农业水土工程、道路交通工程，基础工程，生产粘土、废渣制品等。
