摘要

The paper presents the effect of untreated and chemically treated coir geotextiles on the interface properties of sand-/clay-coir geotextile interface. For this purpose, two woven and two non-woven coir geotextiles were used. The chemicals used for the treatment of coir geotextiles were p-aminophenol, sodium periodate and sodium hydroxide. The results indicated that the adhesion at the clay-/sand-coir geotextile interface with treated woven coir geotextiles was higher in comparison with the untreated woven coir geotextiles. The interface friction angle at the clay-/sand-coir geotextile interface with the treated woven coir geotextiles was less in comparison with the untreated woven coir geotextiles. The adhesion as well as interface friction angle at the clay-/sand-coir geotextile interface with treated non-woven coir geotextiles was higher in comparison with the untreated non-woven coir geotextiles. For the sand-coir geotextile interface with untreated non-woven coir geotextiles, the observed adhesion as well as interface friction angle was higher in comparison with the clay-coir geotextile interface. For the sand-coir geotextile interface with untreated woven coir geotextiles, the observed adhesion was less in comparison with the clay-coir geotextile interface, whereas the interface friction angle was higher for the sand-coir geotextile interface in comparison with the clay-coir geotextile interface.
