Formula of magnesium cement solidified radioactive waste resin and preparation method of magnesium cement solidified radioactive waste resin
The invention discloses a formula for curing waste resin by utilizing hydrated magnesium silicate cement and a preparation method of the formula, and relates to the technical field of radioactive waste treatment. Waste resin is a medium-level radioactive waste, hydrated magnesium silicate cement serves as a curing base material of the waste resin, and the waste resin is prepared from, by mass, 30-50 parts of magnesium oxide, 50-70 parts of silica fume, 90-110 parts of aggregate, 2-4 parts of additive, 30-50 parts of waste resin and 50-60 parts of water. The materials are uniformly mixed in a stirring pot and then poured into a test mold for curing, and the compressive strength of a cement curing body after curing for 28 days can reach more than 7MPa. After waste resin is solidified by the hydrated magnesium silicate cement, the surface of a solidified body is free of cracks and small in strength loss after tests of impact, freeze thawing, soaking and the like, all properties can meet construction standard requirements, recovery of radioactive waste and guarantee of subsequent safety are achieved, and environmental protection is facilitated.
本发明公开了一种利用水化硅酸镁水泥固化废树脂的配方及其制备方法，涉及放射性废物处理技术领域。废树脂是一种中水平放射性废物，本发明将水化硅酸镁水泥作为废树脂的固化基材，按质量份数计，其组成如下：氧化镁30～50份、硅灰50～70份、骨料90～110份、添加剂2～4份、废树脂30～50份以及水50～60份。将上述物质在搅拌锅内混合均匀后倒至试模中养护，养护28天水泥固化体抗压强度可达7MPa以上。本发明的水化硅酸镁水泥固化废树脂后，经冲击、冻融、浸泡等试验后固化体表面无裂纹，强度损失小，各方面性能均能满足施工标准要求，本发明实现了对放射性废物的回收及后续安全性的保障，有利于环保。
