Quality Acceptance Testing of GCLs for Landfill Application

Approximately ten years ago remedial actions started at Jakusevec, the major unsanitary open dump in the vicinity of Zagreb. According to quality assurance testing program, mineral composition, swell index, fluid loss and water absorption capacity of GCLs bentonite component were determined. During remediation works three types of bentonites were tested prior to GCLs installation and it was proven that they meet the project requirement.

Yet a subsequent consideration initiated a series of new tests which have been performed on one type of bentonite immersed into the site specific leachate during different periods of time prior to testing. These results are described in the paper. From the present results it may be concluded that there is no significant influence of leachate to the bentonite behaviour in acceptance tests.
