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.

摘要

本文介绍了化学处理对未处理/处理机织/非织造椰壳土工布耐久性研究的影响. 用对氨基苯酚、高碘酸钠和氢氧化钠处理椰壳土工布. 为此，在万能试验机上对铺设于覆砂粘土界面的未处理/处理的编织/非织造椰壳土工布分别在2、6、8、12个月后进行了室内宽幅抗拉强度试验. 研究结果表明，未经处理和处理的椰壳编织土工布的抗拉强度随时间的增加而降低. 椰子壳机织土工织物的拉伸强度在纬纱方向的降低幅度大于经纱方向. 与未经处理的椰壳土工布相比，处理后的椰子壳土工布的抗拉强度下降幅度更大. 非织造椰子壳土工织物的拉伸强度在纬纱方向的降低幅度大于经纱方向. 未经处理的椰壳无纺布的抗拉强度降低幅度大于处理后的非织造椰壳土工布.
