摘　　要：聚合物水泥用于放射性废离子交换树脂水泥固化工艺,利用其防水性能抑制废树脂的溶胀,降低水泥固化体中放射性核素137Cs9、0Sr浸出率,提高了废树脂包容率和处置的安全性。In tiffs study, polymer cement is added to the formula of cement solidification of radioactive spent ion exchange resin （IER）. The leaching rate of radionuclides such as ^137Cs and ^90Sr from solidified forms is reduced due to the waterproof capability of polymer cement which can restrain the expansion of the spent resin. Therefore, loading capacity of spent IER is increased as well as disposal safety.

关 键 词：聚台物水泥 固化 溶胀 浸出率
