对Cs~+和Sr~(2+)在碱矿渣水泥固化体中的吸附和固溶机理进行了定量研究。结果表明,掺有沸石和硅灰的碱矿渣水泥硬化体具有较强的吸附Cs~+和Sr~(2+)能力以及抗Cs~+和Sr~(2+)脱附能力。XRD分析表明,Cs~+和Sr~(2+)通过替代C—S—H中的Ca~(2+)而被固溶入C—S—H晶格。C—S—H的d_(111)值随CsNO_3和Sr(NO_3)_2掺入量的增加呈限量台阶状增大。SEM/EDS分 The adsorption and solution mechanisms of Cs ~ + and Sr ~ (2+) in alkali slag cement were studied quantitatively. The results show that hardened cement hardened by alkali slag cement with zeolite and silica fume has strong ability of adsorbing Cs ~ + and Sr ~ (2+) and anti - Cs ~ + and Sr ~ (2+) desorption. XRD analysis showed that Cs ~ + and Sr ~ (2+) were dissolved into the C-S-H lattice by substituting Ca ~ (2+) in C-S-H. The d_ (111) value of C-S-H increased with the increase of CsNO_3 and Sr_ (NO_3) _2 increasing in a limited step. SEM / EDS points
