ABSTRACT

India occupied the second position in sugarcane producer country list. Sugar factories produces a huge amount of bagasse ash as a by-product. Bagasse ash is generally used as fertilizer in farming land. However, many scholars argue, it’s not a sustainable means of bagasse ash management as it contains some heavy metals. One of the solutions to this dilemma is the deployment of bagasse ash as a prospective backfill material for geotechnical engineering applications. However, a comprehensive study of bagasse ash as an alternative back-filling material and its behaviour with reinforcement is significantly lacking. This paper presents a study on the utilisation of bagasse ash as a sustainable substitute of natural backfill material and its interaction with geogrid. A series of direct shear tests were conducted for this purpose. The interface shear strengths of bagasse ash—geogrid and geosynthetics—soil were found to be similar.
