采用批试法和柱迁移实验研究了放射性核素 90 Sr、13 7Cs在富铝碱矿渣水泥和 5 2 5 # 水泥中的吸附迁移行为。结果表明 ,富铝碱矿渣水泥对 90 Sr、13 7Cs的吸附比约为 5 2 5 # 水泥的 10倍 ;富铝碱矿渣水泥在阻止放射性核素迁移及浸出性能方面明显优于目前采用的 5 2 5 #水泥
Adsorption and migration of radionuclides 90 Sr and 13 7Cs in Al-rich slag cement and 525 # cement were studied by batch test and column migration experiments. The results show that the adsorption ratio of Al-rich slag cement to 90 Sr and 13 7Cs is about 10 times higher than that of 525 # cement. The Al-alkali-rich slag cement is obviously superior to the current 5 in preventing the radionuclide migration and leaching performance 2 5 # cement
