研究了放射性废物固化材料——富铝碱矿渣黏土矿物胶凝材料(RAAASCM)的组成及其浆体的某些性能。结果表明,热活化高岭土、新疆沸石、改性凹凸棒黏土是富铝碱矿渣黏土矿物胶凝材料较好的组成材料。该胶凝材料浆体具有高强、较低孔隙率、较少的有害孔、抗硫酸盐侵蚀和耐辐照性能好的特点。以此材料为基材的模拟放射性废物固化体Sr2+、Cs+的浸出率较低。
The composition of RAAASCM, a solidified radioactive waste material, and some properties of its slurry were studied. The results show that the heat activated kaolin, Xinjiang zeolite, modified attapulgite clay are the better materials for the aluminate-rich slag mineral clay mineral cementitious material. The cementitious slurry has the characteristics of high strength, low porosity, less harmful pores, good resistance to sulfate attack and radiation resistance. Based on this material, the leaching rate of Sr2 + and Cs + was lower for simulated radioactive solid waste.
