Preparation method of fly ash-mineral powder-stainless steel slag powder ternary geopolymer
The invention discloses a preparation method of a fly ash-mineral powder-stainless steel slag powder ternary geopolymer, which comprises the following steps: S1, using NaOH and water to prepare a NaOH solution, standing and cooling to room temperature; s2, coal ash, mineral powder and stainless steel slag powder are prepared into raw materials according to a certain proportion, the prepared NaOH solution with a certain concentration and the raw materials are stirred for the first time through a stirring machine, and then a certain amount of water glass exciting agent is added to continue to be stirred again; and S3, pouring the stirred slurry into a test mold, performing vibration molding, performing curing for 1-1.5 d, performing demolding, and continuing curing. For the raw material with high calcium content, the stirring process avoids the situation that SiO2 of water glass in the mixed exciting agent is directly subjected to pozzolanic reaction with the raw material during stirring and is rapidly coagulated, the coagulation time is prolonged, and a new process thought is provided for industrial production; silicon-aluminum monomers in the raw materials can be fully dissolved to form a more compact net-shaped structure, so that the strength of the polymer is improved; the water glass consumption can be reduced, and the production cost is reduced.
本发明公开了一种用于粉煤灰‑矿粉‑不锈钢渣粉三元地质聚合物的制备方法，包括：S1、使用NaOH和水配置成的NaOH溶液，静置冷却到室温；S2、将粉煤灰、矿粉和不锈钢渣粉按一定配比配成原料，将配置好一定浓度的NaOH溶液与原料使用搅拌机初次搅拌后，再添加一定量的水玻璃激发剂继续复搅；S3、将搅拌好的浆液倒入试模中振动成型，养护1‑1.5d后脱模，继续养护。对于钙含量高的原料，此搅拌工艺避免了混合激发剂中水玻璃的SiO2在搅拌时与原料直接发生火山灰反应而快速凝结情况，延长凝结时间，为工业化生产上提供了新的工艺思路；可充分溶解出原料中硅铝单体，形成更加致密的网状结构，提高聚合物强度；可减少水玻璃用量，降低生产成本。
