Abstract
This paper presents the Black cotton soil is susceptible to detrimental volume changes due to variation in moisture content. A clay mineral named Montomorillonite which has expanding lattice is responsible to such behavior of this soil because of its special structure and properties it is subjected to appreciable volume changes. The term expansive soil applies to soils that have the tendency to swell when their moisture content is increased and shrink when their moisture content is decreased. The moisture may come from rain flooding, leaking water or sewer lines or from reduction in surface evapotranspiration when an area is covered by a building or pavement.To achieve this problems the soil was treated with waste material The main purpose of this work is waste reduction. Disposal of waste in landfills is not an effective solution in the long term because of limited availability of land resources. Many metro cities in India are already facing problems of finding adequate land for disposal of solid waste for the next 25 to 50 years. The most suitable long term sustainable solution is to reduce the quantity of waste being produced and eventually become a “zero-waste‟ society. Industrial waste reduction can be achieved through adoption of efficient and clean technologies which produce the same quantities of usable products with much smaller quantities of waste and also by recycling or through reuse of the waste material generated. Researchers suggest that these industrial waste materials can be used as a construction material in various applications such as for earth dams, for road and rail embankments, for filling of low lying areas, for embankments of canals and lakes, for backfilling behind retaining structures, etc. several million cubic meters of earth works are executed each year in India alone. If soil could be replaced by waste material in some of these applications would help in reduction/ reuse of these waste materials. Some of these waste materials which meet the criteria of geotechnical characteristics are considered for this soil stabilization purpose. The waste material considered for this project purpose is calcium carbide residue.
