Method for preparing geopolymer cementing material from regenerated micro-powder
The invention discloses a method for preparing a geopolymer cementing material from regenerated micro-powder. The cementing material is obtained by mixing geopolymer powder and an alkali activator, carrying out stirring for a period of time, molding obtained slurry, and carrying out standard maintenance, wherein the geopolymer powder comprises 30-70 wt% of slag powder and 30-70 wt% of regeneratedmicro-powder. The geopolymer cementing material prepared by the invention has high strength and good contractibility and can solve the problem of contraction cracking of common concrete materials; meanwhile, the regenerated micro-powder is used as a raw material, so construction waste is effectively utilized; and the method is a green and environment-friendly method.
本发明公开了一种采用再生微粉制备地聚合物胶凝材料的方法，所述胶凝材料通过将地聚合物粉体和碱激发剂混合后搅拌一段时间，所得浆体成型、标准养护后得到，其中，地聚合物粉体由30~70wt%矿渣粉、30~70wt%再生微粉组成。本发明制备的地聚合物胶凝材料，具有较高的强度，且收缩性良好，可以解决常见混凝土材料收缩开裂的问题，同时，本发明以再生微粉为原料，有效利用了建筑垃圾，是一种绿色环保的方法。
