摘要(Abstract)：

为探究适用于装配式电力工程结构黏接材料的环氧砂浆配合比及其性能，基于正交试验法对不同配比的环氧砂浆力学性能进行测试，采用极差值分析各组分掺量对环氧砂浆1 d抗压、抗折、黏接强度的影响，并选取代表样进行X射线衍射(XRD)与压汞测试(MIP)。结果表明：环氧树脂可有效固化水泥熟料并影响水泥水化进程，同时改变砂浆内部孔隙结构；稀释剂掺量对环氧砂浆力学性能的影响程度最大；水泥与砂的质量比(灰砂比)的增加将阻碍环氧树脂的胶结作用从而影响环氧砂浆的黏接强度；增加固化剂掺量将降低环氧砂浆的韧性。基于正交分析，确定了填料与液料比(F/L)2∶1、固化剂掺量100%(占环氧树脂的量)、灰砂比(C/S)2∶1、稀释剂掺量10%的最优复合环氧砂浆配合比。
