Zusammenfassung:The interaction between compacted bentonite and hardened cement was evaluated. Cement-bentonite-cement-layered test specimens, after infiltrated with water, were subjected to various analyses. The EPMA analysis of the cross sections of the specimens indicated a homogeneous distribution of Ca leached from the cement paste in the bentonite. The quantity of Ca in the bentonite was apparently larger than the cation exchange capacity of the bentonite, suggesting the formation of secondary minerals involving Ca.
