Preparation method of anti-shrinkage all-solid waste alkali-activated cementing material
The invention relates to a preparation method of an anti-shrinkage all-solid waste alkali-activated cementing material. The preparation method comprises the following steps: 1) firstly crushing blocky spontaneous combustion coal gangue by using a crusher, and then carrying out coarse grinding by using a pulverizer; 2) drying the spontaneous combustion coal gangue, the slag and the steel slag in a drying box; (3) putting the materials weighed in the step (2) into a ball mill, and carrying out ball milling for 15 minutes; 4) weighing water, sodium silicate and sodium hydroxide according to a corresponding proportion, putting into a beaker, stirring until cooling, sealing and storing for later use; (5) simply mixing the ball-milled materials, putting the materials into a stirrer, adding an exciting agent solution in 0-10 seconds, slowly stirring for 60 seconds, quickly stirring for 30 seconds, stopping for 90 seconds, scraping the materials into a pot, quickly stirring for 90 seconds, pouring the materials into a mold, vibrating, molding and curing; the prepared cementing material has the advantages of being high in strength, low in cost, small in pollution, good in volume stability, not prone to cracking and capable of achieving resource utilization of solid waste.
本发明涉及一种抗收缩全固废碱激发胶凝材料的制备方法。制备方法为：1)利用破碎机先将块状自燃煤矸石破碎，破碎后利用磨粉机进行粗磨；2)将自燃煤矸石、矿渣、钢渣置于烘干箱中烘干；3)将步骤2中称量好的材料置于球磨机中进行球磨15min；4)将水、硅酸钠、氢氧化钠按照相应比例称量完成放入烧杯中搅拌直至冷却，密封保存备用；5)将球磨好的材料简单拌合后放入搅拌机，0～10s加入激发剂溶液，慢搅拌至60s后快速搅拌30s、停止90s，将材料刮入锅中后再快速搅拌90s后倒入模具，振捣成型并养护；本发明制造的胶凝材料具有强度高、成本低、污染小、体积稳定性好、不易开裂、将固废资源化利用的优点。
