Method for preparing soil stabilizer by compounding bulk industrial solid wastes and application of soil stabilizer
The invention relates to the technical field of curing agents, in particular to a method for preparing a soil curing agent by compounding bulk industrial solid waste and application. The method comprises the steps of A component raw material treatment, A component soil stabilizer preparation, B component raw material treatment, B component soil stabilizer preparation, C component raw material treatment and C component soil stabilizer preparation. The method comprises the following steps: adding water into CaO in industrial solid waste high-calcium ash to release heat, and adding industrial byproduct gypsum to generate the required composite exciting agent; adding red mud or carbide slag for dehydration to obtain an alkali activator Ca (OH) 2 at the same time; and taking CaCO3 in the crushed high-calcium ash as a skeleton to increase the strength of a consolidated substance. Three soil stabilizers can be prepared according to different engineering properties and can be used independently or compositely. Calcination is not needed in the whole preparation process, energy consumption and use of natural resources are reduced, the production cost is low, and no three wastes are discharged; the method has the advantages of wide application field, strong pertinence, stable quality, high solid waste utilization rate and no secondary pollution after use.
本发明涉及固化剂技术领域的一种复合大宗工业固废制备土壤固化剂的方法与应用；包括A组份原料处理、A组份土壤固化剂制备、B组份原料处理、B组份土壤固化剂制备、C组份原料处理、C组份土壤固化剂制备。本发明利用工业固废高钙灰渣中的CaO加水放热，加入工业副产石膏，生成所需的复合激发剂；加入赤泥或电石渣进行脱水，同时得到碱激发剂Ca(OH)2；破碎后高钙灰渣中的CaCO3作为骨架增加固结物的强度。根据不同的工程性能，制备出三种土壤固化剂，可单独或复合使用。整个制备中无需煅烧，减少了能耗和天然资源的使用，生产成本低且无三废排放；应用领域广、针对性强、质量稳定、固废利用率高，用后无二次污染。
