Quality acceptance testing of GCLs for landfill applications

In order to fulfill the requirements for landfill applications, GCLs were subjected to the manufacturing quality control during the production and to the quality assurance procedures at construction site. According to quality assurance testing program at the Jakusevec landfill, mineralogical and physical properties of bentonite component were determined. Testing program consisted of: XRD-analysis, swell index test of clay mineral component of GCL (ASTM D 5890), fluid loss test of clay component of GCLs (ASTM D 5891-95) and water absorption capacity (DIN 18 132). Swell index (free swell) and water absorption capacity (Figure 1) are index tests which quantify the swelling property of GCLs mineral component. These test methods are useful for establishing the relative quality of a clay component in a simple and quick way. Fluid loss is a very quick method of determining a bentonite's ability to perform as a hydraulic barrier i.e. to create a seal. A low fluid loss value indicates a low permeability value, too. Some test results are presented in the paper for two types of GCLs. By the comparison of prescribed and measured values it can be concluded that these two types of GCLs fulfill, in general, the project requirements.
