Geopolymer and preparation method thereof
The invention relates to the field of building materials, in particular to a geopolymer and a preparation method thereof.The geopolymer is prepared from, by weight, 0%-41.4% of silty-fine sand, 6.1%-39.4% of coal gangue, 2.0%-12.8% of blast furnace slag, 2%-4% of a polyacrylamide-based internal curing agent and 46%-55% of an alkaline exciting agent, and the alkaline equivalent of the alkaline exciting agent is 7%-13%; the modulus of the alkaline activator is 0.8-1.5; the liquid-solid ratio is 0.35 to 0.5. The preparation is prepared by stirring and mixing. The utilization rate of solid waste is increased, and meanwhile the early compressive strength is improved.
本发明涉及建筑材料领域，具体涉及一种地聚物及其制备方法，以重量百分比计，其各组分含量为：粉细砂0～41.4％，煤矸石6.1～39.4％，高炉矿渣2.0～12.8％，聚丙烯酰胺基内养护剂2～4％，碱性激发剂46～55％，其中碱性激发剂碱当量7～13％；碱性激发剂模数0.8～1.5；液固比0.35～0.5。通过搅拌混合而成。本发明提高了固体废弃物利用率，同时提高了早期抗压强度。
