Title

STABILIZATION/SOLIDIFICATION (S/S) OF COPPER CONTAMINATED SOIL

Abstract

The industrial slag and e-waste which contains a high concentration of lead, nickel, zinc, copper etc. Such type of waste is disposed to open environment cause health issue like liver damage, kidney disease, and several others health problem. When this contaminant comes in contact with the soil, the geotechnical properties of soil is altered and water-soluble contaminant is transported in the direction of the groundwater flow. The present study describes the geotechnical behavior of artificially copper contaminated soil stabilization of the copper contaminated soil. The stabilization/solidification (S/S) is a remedial technique which is used to stabilize the contaminated soil. The binder which used for the stabilization purposes that create a layer on the contaminant and encapsulate in the solid matrix. Use of fly-ash as binding material help to stabilize two waste material into the stable solid matrix. For the study purpose, three different soil-binder ratios are selected for treatment, in which micro fine cement differ up to 5%, 10%, 15% and fly ash is varied up to 10%, 20%, 30% by weight. For the economical reason micro fine cement is not used more than 15% and fly ash is waste material so using that waste also helps to economize the mix. The effectiveness of the treatment was assessed by the physical testing of the solidified soil-cement-fly ash mixture using Unconfined Compressive Strength (UCS), Energy-dispersive X-ray spectroscopy (EDS) and Scanning Electron Microscopy (SEM). Additionally, column leaching tests were performed to identify the property of the leachate. Durability study of the stabilization was verified using wetting and drying cycles of 12 days with alternating the wetting and drying sessions. The results showed the contaminant changes the geotechnical properties of soil. The contaminant causing a decrease in the liquid limit, maximum dry density (γd max) and angle of internal friction (ϕ). Also, increase in the specific gravity (G) of soil and optimum water content. The contaminant decreases the compressive strength of soil by 26% compared to natural soil.

Key Words
