Preparation method of waste slag modifying additive
The invention relates to a preparation method of a waste slag modifying additive. The method comprises the following steps of: A, weighing raw materials in percentage by weight, putting water into a container, sequentially adding 1-3% of metal cation chelate, 0.01-0.035% of nano cerium oxide and/or nano lanthanum oxide and 0-0.5% of quinoline oxide, and stirring the materials at normal temperaturefor 3-5 minutes; B, after uniformly stirring the materials, sequentially adding 1-5% of manganese sulfate, 0-2% of polyethylene ethanol and 0-4% of retarder, and continuously stirring the mixture for5-10 minutes; and C, finally, adding 0.1-0.2% of cross-linking agent, 1-5% of silica gel and 0-0.8% of glucose, and stirring the mixture for 5-10 minutes to prepare the waste slag modifying additive.After the waste slag modifying additive disclosed by the invention is added into waste slag, the modified waste slag has flexibility and rebound property under the pressing of external pressure, canreach the strength of concrete, has pressure resistance, has strong resistance to water, and has higher strength under the erosion of water; and the modified waste slag can be directly used as a building material for replacing cement.
本发明涉及一种废料矿渣改性添加剂的制备方法，包括以下步骤：A.按重量百分比称量原料，将水置于容器中，依次加入1‑3％的金属阳离子螯合物、0.01‑0.035％的纳米氧化铈和/或纳米氧化镧、0‑0.5％的氧化喹啉在常温下搅拌3‑5分钟；B.搅拌均匀后，然后再依次添加1‑5％的硫酸锰、0‑2％的聚乙醇、0‑4％的缓凝剂，继续搅拌5‑10分钟；C.最后加入0.1‑0.2％的交联剂、1‑5％的硅胶和0‑0.8％的葡萄糖，搅拌5‑10分钟后配制废料矿渣改性添加剂。将本发明的废料矿渣改性添加剂添加到废料矿渣后，改性后的废料矿渣在外界压力的压制下具有柔性、反弹性，可达到混凝土的强度，并具有抗压性，对水具有很强的抵御能耐，并在水的侵蚀下其强度更大；能够直接一种作代替水泥的建筑材料使用。
