Research Abstract

This research aims to establish proper countermeasures for the utilization of soils and rocks potentially containing metals and/oracidity. From the experimental results, following issues were verified:
1) Geosynthetic clay liner(GCL) shows low hydraulic conductivity when the bentonite can be sufficiently swelled
2) GCL can perform relatively high metal attenuation capacity against the solutions containing metals and comparatively high acidity
3) Arsenic in a solution is immobilized on the other precipitated metals coexisting in the solution through a surface complexation reaction, and
4) A hydraulic conductivity of bentonite-based materials, such as GCL and soil-bentonite mixture, increased under the conditions thatthe swelling of bentonite is inhibited.
