Cement material for solidifying radioactive waste and use method thereof
The invention belongs to the field of radioactive waste disposal, and particularly discloses a cement material for solidifying radioactive waste and a using method thereof.The cement material is prepared from, by weight, 60-75 parts of a cement base material, 1-2 parts of a retarder, 0.2-0.7 part of a water reducing agent and 2-5 parts of fly ash, and the retarder comprises sulfonic acid groups and a five-membered ring structure. The cement curing material is suitable for solid radioactive wastes, and the cured product has few cracks, low porosity and good retention effect on nuclides.
本发明属于放射性废物处置领域，具体公开了一种用于固化放射性废物的水泥材料及其使用方法，按重量份计，该水泥材料包含以下原料：60‑75份水泥基材、1‑2份缓凝剂、0.2‑0.7份减水剂和2‑5份粉煤灰，其中缓凝剂包含磺酸基团和五元环结构。该水泥固化材料适用于固体放射性废物，并且固化产物裂纹少、孔隙率低，对核素的滞留效果较好。
