摘　　要：研究了固化剂掺量、稀释剂掺量和石英砂填料掺量对环氧树脂砂浆的工作性能和力学性能的影响规律。结果表明:固化剂和稀释剂对环氧树脂砂浆的性能影响最为显著,其次是石英砂填料,固化剂、稀释剂、填料均对环氧树脂砂浆得流动度较大影响,可将环氧树脂砂浆得流动度在146~205mm之间变化。固化剂和稀释剂对凝结时间影响最为显著,填料影响次之,凝结时间可在143~285min之间变化。使用30份固化剂、15份稀释剂和20%填料掺量环氧树脂砂浆具有最好的力学性能,1d抗压强度和抗折强度能达到82.3MPa和23.9MPa。Studies the curing agent dosage,diluent dosage and quartz sand filler dosage of epoxy resin mortar working performance and mechanical properties of the influence law.The results show that:curing agent and diluent on the performance of epoxy resin mortar is the most significant,followed by quartz sand filler,curing agent,diluent,filler are on the epoxy resin mortar flow rate of greater impact,can be epoxy resin mortar flow rate between 146~205 mm change.The curing agent and diluent on the setting time is the most significant,the filler effect is second,setting time can be 143~285 min change.Using 30 curing agent,15 diluent and 20% filler dosage of epoxy resin mortar has the best mechanical properties,1 d compressive strength and bending strength can reach 82.3 MPa and 23.9 MPa.
