| 摘 要： | 研究了新型放射性废物固化胶凝材料—富铝碱矿渣粘土矿物胶凝材料（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、改性凹凸棒粘土是富铝碱矿渣粘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。

| Abstract: | The composition of new cementitious materials-rich alumina alkali-activated slag clay minerals (RAAASCM) cementitious materials for immobilization of radioactive wastes and some properties of it's pastes are studied. Experimental results show that heat activated kaolinite,Xingjiang zeolite,modified attapulgite clay are better constituents of RAAASCM. RAAASCM cementitious materials pastes exhibit high strength,low porosity,fewer harmful pore,high resistance to sulphate corrosion and to gamma irradiation.The Sr 2 ,Cs leaching rate,of the simulated radioactive waste forms based on RAAASCM,are low. |
