摘　　要：对混凝土高整体容器(HIC)用密封材料的耐久性进行研究,探讨了环氧乳液掺量对混凝土HIC用密封材料抗冻性能、抗硫酸盐侵蚀性能的影响规律。研究结果表明,聚灰比为6%时,混凝土HIC用密封材料的抗冻性能、抗硫酸盐侵蚀性能最佳,且按此配合比配制的密封材料其碳化性能、耐辐照性能及渗透性能也均符合《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 concrete＇ high integrity container （HIC） sealing material,the influence of different e- poxy emulsion dosage on anti-frost property and sulfate attack resistance of concrete HIC sealing material was explored. Result shows that the anti-frost property and sulfate attack resistance of concrete HIC sealing material were best when the polymer-ce- ment ratio was 6%,and carbonization resistance,irradiation resistance and penetrating quality of concrete HIC sealing material met the requirements of standard：The low,high level radioactive waste in the high overall container-concrete container. Then itsmechanism was analyzed.
