摘要
研究了不同水热条件下粒化高炉矿渣(granulatedblast-furnaceslag,简写GBS,以下简称为矿渣)加入“碱-偏高岭土”体系后,其水化产物对Sr、Cs的吸附性能影响和力学性能变化;通过体系对Sr、Cs吸附性能和力学性能的变化情况,进一步研究了掺废液体系KS20经不同水热条件处理后,产物对废液离子浸出性能的影响。结果表明:“碱-偏高岭土”体系加入矿渣后,体系对Sr、Cs的吸附性能随矿渣加入量增加而降低;强度随矿渣加入量增加而提高;掺废液体系KS20合成温度升高,废液掺量增加,废液离子浸出百分数不断减少。
The influence on the absorption property of Sr and Cs and the mechanical properties of different hydrothermal synthesized products were studied after dosage different slag GBS （ granulated blast-furnace slag） to the ＂alkali-metalkaolin＂ system . According to changed laws of absorption property of Sr and Cs and the mechanical properties of different hydrothermal synthesized products, further research that the immobilization properties of waste liquid form of KS20 which were synthesized by means of different hydrothermal treatment were carried. The results show that hydrothermal synthesized products＂ absorption properties of Sr and Cs will decrease with increase of dosage of slag while compressive strength will change reversely, after slag was added to ＂alkali-metalkaolin＂ system, and that KS20 waste forms＇leaching fraotiens of waste liquid ions will decrease with increase of dosage of waste liquid and suring temperature.
