在对辽宁阜新高德矿自燃煤矸石进行了基本性质检测的基础上,采用物理和化学的激活方法,研究了自燃煤矸石胶结料的力学性能.物理研究表明该矸石易磨性较好;对以自燃煤矸石为主要材料的胶结料进行了正交试验研究,分析了矿粉、生石灰、二水石膏及水玻璃掺量对胶结料强度的影响.化学研究表明自燃煤矸石在复合激发剂的共同作用下,高掺量(74%)仍可配制出满足42.5强度等级的水泥.根据正交设计方差分析结果给出了胶结料的最佳配合比,为利用自燃煤矸石开发地聚物水泥提供了有益的技术参考.

The mechanical properties of spontaneous combustion coal gangue's bonding material was researched by physical and chemical activation method.The research is based upon checking the element property of spontaneous combustion coal gangue in Gaode Mine,Fuxin city of Liaoning Province. The physical research showed that this coal gangue has good grindability;the orthogonal test on the bonding material which take the spontaneous combustion coal gangue as the primary material analysis the influence of powdered ore,calcium oxide,dihydrate gypsum and sodium silicate's content on bonding material's strength. Chemical research showed that spontaneous combustion coal gangue can still make C42.5 cement with high content (74%) under the interaction of compound activation. According to analysis of variance results, we are able to determine the optimum mix proportion of bonding material which can provide useful technical reference to exploit geopolymer cement from spontaneous combustion coal gangue.
