High-compactness radioactive solid waste fixing body
The invention discloses a high-compactness radioactive solid waste fixing body, which is prepared from the following ingredients in percentage by weight: 60 to 70 percent of waste bodies, 10 to 15 percent of binding materials, 10 to 15 percent of aggregates, 0.1 to 0.2 percent of efficient water reducing agents, 2 to 4 percent of coal ash, 7 to 10 percent of water and 0.1 to 0.2 percent of air entraining agents. According to the invention, a cementing material is adopted as a fixing material and can be changed into a firm stone-shaped body from slurry through a series of physical and chemical actions, and other solids can be cemented into a substance with certain mechanical strength. The fly ash is also added, and the fly ash can reduce the use amount of a cementing material so as to achieve the effects of reducing hydration heat and reducing the water consumption; in addition, the fly ash can also increase the use amount of the air entraining agent, and the air entraining agent can introduce a large amount of uniform, stable and difficult-to-damage tiny bubbles into the mortar, so that the pore structure of a fixed body can be improved, and the impermeability of the mortar is greatly improved.
本发明公开了一种高致密性放射性固体废物固定体，包括以下重量百分比的组分：废物体60‑70％，胶凝材料10‑15％，骨料10‑15％，高效减水剂0.1‑0.2％，粉煤灰2‑4％，水7‑10％，引气剂0.1‑0.2％。本发明采用胶凝材料为固定材料，其经过一系列的物理、化学作用，能从浆体变成坚固的石状体，并能将其他固体胶结成具有一定机械强度的物质。本发明还添加粉煤灰，粉煤灰可以减少胶凝材料的使用量，以达到降低水化热的作用和减少用水量；另外粉煤灰还可以增加引气剂的用量，引气剂可以向砂浆引入大量均匀、稳定且不易破坏的微小气泡，可以改善固定体的孔结构，大幅提高其抗渗性。
