Study about Swelling Behaviour of Black Cotton Soil with Fly Ash

Rajendra Prasad Hardaha | Mohan Lal Agrawal | Anita Agrawal ^[2]

Abstract: Black Cotton soil is good for agriculture purpose but dangerous for construction point of view. In the region of Black Cotton soil (or say Expansive soil), swell-shrink behaviour is risky for the structure. In this research, fly ash has been used to stabilize the soil so that its swelling behaviour may control and becomes very small. Fly ash is the fine residue obtained from the thermal power stations using pulverised coal as boiler fuel. It poses the dual problem of disposal and environmental pollution and hence generally treated as waste. The present paper deals with the evaluation of Free swell index of black cotton soil with fly ash, which are individually determined first and then combined in varying proportions. From Preliminary investigations it can be said that free swelling index can be reduced in Black Cotton soil by the use of fly ash.
