AUGMENTING THE GEOTECHNICAL CHARACTERISTICS OF SOIL BY DRY BAGASSE AND FLY ASH

Tanu Kumar and Ashok Kumar Gupta

Abstract

Increase in industrialization and urbanization has resulted in pollution of available land, and most of the agricultural land has turned into construction sites lately. Large proportion of the agricultural land is black cotton soil having high swelling and shrinkage property. Thus the soil should be treated or replaced with a suitable and effective material to enhance its mechanical properties for construction of buildings, referred as soil stabilization. Cost-effective and economically feasible solutions for waste management are the valorisation of waste from sugarcane industries using dry bagasse and fly ash from coal power plants in improving soil characteristics. This review provides comprehensive understanding on use of fly ash in combination with dry bagasse as an effective soil stabilizer.
