Abstract:
Black cotton soils are problematic to civil engineering structures they undergo large volume changes due to variation in water content. Montmorillonite is the major clay mineral present in the Black cotton soil. In order to improve their properties, different admixtures are used. Among them fly ash, which is the byproduct of combustion of pulverized coal in thermal power plants is being increasingly used. Industrial activity is necessary for the social-economic progress of a developing Country but at the same time it generates large amount of solid and liquid waste. These wastes contain different types of chemicals both in solid and liquid form. These chemicals consist of different chemical compositions which alter the geotechnical properties of soil by reacting with the chemical composition of soils. Soils when contaminated with chemicals, significant change in their volume is observed. This paper presents the experimental programme on compaction characteristics of black cotton soil treated with fly ash and lime in presence of varying percentages of alkalis. Alkalis used in the present study are calcium carbonate and magnesium carbonate, both ranging from 5% - 20%. On addition of calcium carbonate to BCS-FA-Lime mixture maximum dry density of BC soil increases from14.74kN/m3 to 14.88kN/m3 and optimum moisture content of BC soil decreases from 31% to 25.4% respectively, on addition of magnesium carbonate maximum dry density of BC soil decreases from14.7kN/m3 to 11.1kN/m3 and optimum moisture content of BC soil increases from 31% to 47.8% respectively. Based on the present study it can be concluded that compaction characteristics improves with calcium carbonate compared to magnesium carbonate.
