Effect of Chemical Treatment on the Durability Behavior of Coir Geotextiles

Abstract

The paper presents the effect of chemical treatment on the durability study of untreated/treated woven/non-woven coir geotextile. The p-aminophenol, sodium periodate, and sodium hydroxide were used for the treatment of the coir geotextiles. For this, laboratory wide width tensile strength test was conducted in a universal testing machine for untreated/treated woven/non-woven coir geotextile placed at the interface of sand-overlaying clay after the period of 2, 6, 8, 12 months, respectively. The results of this study reveal that the tensile strength decreased for the untreated and treated woven coir geotextiles with increase in the period. The reduction in the tensile strength for the woven coir geotextiles was more in the weft direction as compared to the warp direction. The reduction in the tensile strength of the treated woven coir geotextiles was more as compared to the untreated coir geotextiles. The reduction in the tensile strength for the non-woven coir geotextiles was more in the weft direction as compared to the warp direction. The reduction in the tensile strength for the untreated non-woven coir geotextile was more as compared to the treated non-woven coir geotextiles.
