Study on Cementation Formulation of Simulated Radioactive Fluoride Liquid Waste
摘要
Abstract
In this paper ,the formulation with ratio of m(zeolite)∶ m(silica fume)∶ m (quartz sand)∶ m(cement)=1∶1∶3∶10 was used to solidify the simulated radioactive fluoride liquid wastes . The fluidity and setting time of the cement slurry meet the requirements of in‐drum cement solidification .28 d compressive strength and strength losses after water/freezing resistance tests were investigated ,and the shock resistance and leaching nuclide test were also conducted .The results show that it is feasible to solidify simulated radioactive fluoride liquid wastes with the formulation as prepared . The 28 d compressive strengths ,strength losses after tests and simulated nuclide leac‐hing rates of the cement solidified waste form meet the demands of GB 14569.1—2011 . Leaching rate of fluoride ion in the cement solidified waste form is very low .XRD pat‐terns show that fluoride ion is in the form of CaF2 .The suitable content of fluoride ion in the liquid wastes is 1% ,the final setting time of the cement solidified waste form is 14 h ,and the leaching rate of the fluoride ion is 2.54 × 10-3 cm/d after 42 d .关键词
