Adhesion at jute geotextile/clay slurry interface

Abstract

The interface behavior between the jute geotextile and various clay types commonly found in dredged seabed soils is a critical factor in ensuring the effective use of jute fabric for the layered clay-jute geotextile-sand method for land reclamation. In the present work, the effects of clay-type was examined using clays of liquid limits ranging from 100% to 400%, prepared from various mixes of Kaolin-Bentonite. Using the vertical sheet test, the interface adhesion between the jute and four samples of Kaolin-Bentonite mixes were measured. When the water contents are normalized by the liquid limits, it was observed that the interface adhesion values fall into a very narrow behavior band, thus making it possible to estimate the available interface strength between jute and clay slurry based on water contents.
