高温条件下での鉄-ベントナイト相互作用を対象に、ベントナイトの変質に影響を及ぼすと考えられる要因(スメクタイト組成,溶液条件,鉄-ベントナイト比)をパラメータとした変質実験を行った。結果として、温度だけでなく、今回考慮したような要因も変質挙動に与える影響が大きいことが示唆された。

To investigate bentonite-iron interaction under high temperature condition, alteration experiments considering several factors (smectite composition, solution chemistry, iron-bentonite ratio) which were believed to affect on bentonite alteration were conducted with different experimental conditions. As the results, it was suggested that the factors considered in this study could also significantly affect on bentonite alteration in addition to temperature condition.
