Uranium tailing curing agent and curing method thereof
The invention provides a uranium tailing curing agent and a curing method thereof, and belongs to the technical field of uranium tailing curing treatment. The uranium tailing curing agent comprises a cementing material, fine aggregate and water, the mass ratio of the cementing material to the fine aggregate to the water is 1: (1-3): (0.44-0.46), the cementing material is composed of mineral powder and sodium silicate, and the fine aggregate is composed of river sand and uranium tailings. During curing, firstly, the mineral powder and the sodium silicate are mixed, then the fine aggregate and the water are sequentially added, curing is conducted after mixing, and the uranium tailing solidified body can be obtained. The mineral powder is added into the uranium tailing curing agent, a traditional cement curing mode is replaced, the use amount of cement is reduced, and meanwhile carbon emission can be reduced. The strength of the obtained uranium tailing solidified body can reach 65.2 MPa to the maximum degree, a soaking experiment is carried out on the solidified body, the appearance of the solidified body does not have obvious cracks or cracks, and the uranium tailing solidified body has good soaking resistance.
本发明提供了一种铀尾渣固化剂及其固化方法，属于铀尾渣固化处理技术领域。本发明的铀尾渣固化剂包含胶凝材料、细骨料和水，其中胶凝材料、细骨料和水的质量比为1：1～3：0.44～0.46，胶凝材料由矿粉和硅酸钠组成，细骨料由河砂和铀尾渣组成。固化时首先将矿粉和硅酸钠混合，之后顺次加入细骨料和水，混合后进行固化，即可得到铀尾渣固化体。本发明通过在铀尾渣固化剂中添加矿粉，代替了传统的水泥固化方式，减少了水泥的用量，同时可以降低碳排放。本发明得到的铀尾渣固化体的强度最高可达65.2MPa，对固化体进行浸泡实验，其外观没有明显的裂纹或龟裂，具有良好的抗浸泡性能。
