On the mechanical properties of para rubber-oil palm ash derived geosynthetic clay liner

Abstract

A mixture of kaolinite and oil palm ash with latex binder were from to make a core of the geosynthetic clay liner. Then, it was covered by latex-coated calico. The GCL developed had the width and length of 100 cm and 200 cm, with the total thickness of about 7 mm. It is to be used as liner at the bottom of a landfill in order to prevent the leachate to have a contact with the groundwater that could harm people who make use of that contaminated water. Several laboratory tests were carried out to evaluate whether it has the same properties as commercial ones; and, it can be employed in field. Only punching shear resistance and tensile strength are reported in this paper. It was found that both tests yield results that are in accordance with the industrial standard, indicating that it can be really employed in the field.
