摘　　要：研究了SM高效减水剂对浇注料流动值和力学性能指标的影响,以及添加锆英石粉对耐火浇注料热震后残余抗折强度的影响。结果表明,在试验范围内随SM加入量增大浇注料流动值增大,体积密度增大,显气孔率降低,耐压强度、抗折强度增大;随锆英石加入量增加,热震15次后残余抗折强度先增大后减小。The effect of SM high-efficiency water reduction agent on indexes of flow value and mechanical property of refractory castable and effect of addition of zirconite powder on residual strength after thermal shock of refractory castable are studied.The results show that in the test range,with the increase of SM addition,flow value is increased,bulk density is increased,apparent porosity is reduced,the crushing strength and modulus of rupture are raised;with increase of zircon addition,the residual modulus of rupture after 15 thermal shocks is first increased and then reduced.
