| 中文摘要 | 为提高煤矸石的综合利用率,以500℃煅烧的煤矸石为主体原料,附以改性硅酸钠溶液为成岩剂,研制煤矸石质硅铝基胶凝材料.利用煤矸石与矿渣、粉煤灰之间的协同效应在常规条件下制备出强度持续增长(62.10 MPa,3 d;93.15 MPa,90 d)、施工性能良好的胶凝材料.通过X射线衍射、IR和MAS NMR对全煤矸石硅铝基胶凝材料进行研究,煤矸石质硅铝基胶凝材料在水化前后Si,A l价键和配位发生了改变,表征有水化产物生成,进一步验证水化产物有水白云母、C-S-H凝胶和类沸石无定性铝硅酸盐凝胶.根据煤矸石硅铝基胶凝材料的特征提出了原位键合的水化机理.; High performance gangue-containing aluminosilicate based cementitious materials were produced with gangue calcined at 500 ℃ and modified alkali silicates solutions as diagenetic admixture.Cementitious materials with compressive strength growth increasingly(62.1 MPa curing for 3 d and 93.15 MPa curing for 90 d) and favorable construction performance were produced through making full use of the synergistic effect of the compound of gangue,slag and fly ash.Gangue-containing aluminosilicate based cementitious materials were studied by the methods of XRD,SEM,IR and MAS NMR.The results show that the change of valence-bond and coordination changes for Si and Al.Muscovite,C-S-H gel and a zeolite-like material were found in hydration production.Based on the properties of gangue-containing aluminosilicate based cementitious materials,in situ bonding hydration mechanism was put forward.; 国家自然科学基金资助项目(50474002); 教育部科学技术研究项目(104231); 国家“863”计划基金资助项目(2003AA332020) |
