【摘要】 膨润土的热学性能是评价膨润土作为高放废物深地质处置库缓冲/回填材料的重要参数。高庙子膨润土矿床初步确定为中国缓冲/回填材料的供应基地,本研究通过实验,获得了高庙子膨润土的导热系数。结果表明,在相同的压实密度条件下,随着膨润土含水率的增加,导热系数也增加。更多还原

【Abstract】 The heat conductivity of bentonite is one of the important parameters for buffer/backfilling materials as barriers in high level radioactive waste disposal system.The laboratory tests indicate that the heat conductivity of bentonite is correspondent to the charge of water content in bentonite.The heat conductivity of bentonite will increase with the rising of water content in bentonite under the same compact density.更多还原
