Preparation method of environment-friendly mortar
The invention discloses a preparation method of environment-friendly mortar. The environment-friendly mortar comprises the following components in parts by weight: 0-20 parts of ordinary Portland cement; 8 to 20 parts of high-calcium desulfurized fly ash; 10 to 70 parts of tungsten tailing powder; 30 to 90 parts of mineral powder; 30 to 90 parts of fine aggregate; 20 to 65 parts of fine aggregate; 0 to 250 parts of cement; 1-3 parts of a foaming agent; 1-3 parts of a stabilizer; 0-8 parts of an alkaline activator; 1-5 parts of a water reducing agent; and 1-3 parts of a water retention thickening agent. The tungsten tailing powder is recycled to replace cement as a cementing material, so that resources are saved, and the industrial solid waste treatment cost is reduced; the tungsten tailing powder geopolymer mortar can be applied to road cushions, pipe gallery cushions and the like, raw materials are easy to obtain, the preparation cost is low, good economic benefits and social benefits are generated, and the tungsten tailing powder geopolymer mortar has the advantages of being rapid in hardening, high in strength, low in permeability, good in durability, low in carbon and environmentally friendly.
本发明公开了一种环保型砂浆的制备方法，按重量份数计包括以下组分：普通硅酸盐水泥：0～20份；高钙脱硫灰：8～20份；钨尾矿粉：10～70份；矿粉：30～90份；细骨料：30～90份；细骨料：20～65份；水泥：0～250份；发泡剂：1～3份；稳定剂：1～3份；碱性激发剂：0～8份；减水剂：1～5份；保水增稠剂：1～3份。本发明回收利用钨尾矿粉替代水泥作为胶凝材料，有利于节约资源，减少工业固废处理成本；钨尾矿粉地聚物砂浆可应用于道路垫层、管廊垫层等，原材料易得，制备成本低，产生较好的经济效益和社会效益，还具有硬化快、强度高、渗透率低、耐久性好和低碳环保的优点。
