摘　　要：研究以油页岩冶炼飞灰、水泥熟料、石膏等为主要原料的胶凝体系。在选定胶凝体系激发剂种类的基础上,对激发剂的组合以及掺量进行优选。结果表明:在标准养护条件下,当油页岩冶炼飞灰为64%、熟料21.5%、石膏6%、激发剂1为2%、激发剂2为0.5%,激发剂3为6%时,可制备28d抗压强度达45MPa的胶凝材料。The cementitous system prepared by smelt fly-ash of oil shale,clinker and gypsum was studied in this paper. Based on the chosen activator kinds of cementitious system,the combination and concentration of activator were optimized. It is proven that under the standard curing conditions,the 28 d compressive strength of the cementing material is up to 45 MPa ,when smelt fly-ash of oil shale,clinker,gypsum,activator 1,activator 2 and activator 3 are 64%,21.5%,6%,2%,0.5% and 6% respectively.
