摘　　要：针对混凝土高整体容器（HIC）用密封材料力学性能进行研究，探讨环氧乳液掺量对混凝土HIC用密封材料抗压强度、抗折强度及拉拔粘结强度的影响规律。研究结果表明：随着聚灰比的增大，混凝土HIC用密封材料的抗压、抗折及拉拔粘结强度均呈先提高后降低的趋势；当聚灰比为2％～8％时，混凝土HIC用密封材料在满足自流平灌注工艺要求的前提下，其力学性能均能符合正在编制的《低、中水平放射性废物高整体容器——混凝土容器》标准要求。并对其机理进行分析。According to the research of the mechanical properties of concrete high integrity container （HIC） sealing material, this paper explored the influence of different epoxy emulsion dosage on compressive strength,flexural strength and pullout bond strength of concrete HIC sealing material. The result shows that with the increase of the polymer-cement ratio, compressive strength,flexural strength and pullout bond strength of concrete HIC sealing material are the change trend of first increases and then decreases：when the polymer-cement ratio in 2%-8% range, at the same time concrete HIC sealing material meet self-leveling concrete pouring process ＇requirement,mechanical properties of concrete HIC sealing material can meet the requirement of standard ＂The low,high level radioactive waste in the high integrity container＂. This paper also analyzes its mechanism.
