Environmental Impact Assessment of Soil Stabilization Materials

Abstract

During the past few decades lot of emphasis has been laid upon utilization of waste materials to improve the sustainability in environment. Even though we have been able to successfully utilize the primary waste product but its environmental impact remains the cause of concern. Without determining the toxicity characteristics of compounds formed during the reactions and their potential hazardous characteristics we cannot claim that the added compound has proven to be environment friendly on mere eradication of primary pollutants or waste products. The study has been carried out to determine the formation of compounds on addition of Fly Ash (FA) in soil. X-ray diffraction technique was incorporated in the study to characterize the compounds formed during the analysis. During the course of investigation calcium, aluminum and sulfur-containing compounds were observed. In addition to compounds, a variety of mono-valent, Di-valent ions were also traced. The ecological toxicity level of compounds was determined and compared with the toxicity potential of primary additive compounds.
