含水飽和させた圧縮Ca型モンモリロナイト中の空隙構造を1H NMR法によって分析した。1H NMRで観測される水分子の緩和時間が空隙サイズに依存することを利用して、圧縮Ca型モンモリロナイトの層間と粒子間空隙を定量的に評価した。

A structural analysis of water-filled pores in saturated compacted Ca-type montmorillonite was conducted by 1H NMR spectroscopy. The pore structure including interlayer and intraparticle pores in Ca-type compacted montmorillonite was characterized by relaxation time observed by 1H NMR and their correlations with water-filled pore sizes.
