MODIFICATION STUDIES ON MARINE CLAY REINFORCED WITH JUTE FIBER AND TREATED WITH PHOSPHOGYPSUM AS A STABILIZER

Marine Clays are with behaviour of low shear strength and high moisture content, thereby exhibiting high compressibility. Utilizing such clays for resting the foundations is almost impossible without some means of improving the adverse properties. This gives the need for thinking different alternate stabilization techniques in improving the behaviour of these marine clays. Although several methods, such as prefabricated vertical drains, Geotextile reinforcing, cement and lime stabilization, have been successfully implemented to treat such soils, there always remains the motivation for further improvement of the methods, especially in terms of efficiency. This gives the need for thinking different alternate stabilization techniques in improving the behaviour of these marine clays. The weak marine clay behaviour and the corresponding strength characteristics of these clays are improved by using various additives. The use of reinforcing elements is also being rapidly increasing these days. This led to initiate the present work in studying the effect of phosphogypsum on the properties of marine clay and reinforcing with jute fiber. A systematic methodical process was followed, involving experimentation in the laboratory under controlled conditions.
