Effect of Bagasse Ash and Ferric Chloride on Modification of Soil Properties

Many studies are available to understand the behaviour of soils with inclusion of suitable additives. Locally available materials in the form of waste obtained from industry and agriculture can be used as a stabilizer as a significant cost-effective technique to modify the property of soils. The present paper discusses the influence of bagasse ash and ferric chloride on properties of fine-grained soil. Bagasse ash varying from 5 to 30% and ferric chloride varying from 0.10% to 1.00% respectively were used to investigate the alter in properties of soil. The optimum percentage of ferric chloride and bagasse ash was determined from standard compaction test for different proportions of bagasse ash (BA) and ferric chloride (FC) added to the soil, respectively. The unconfined compressive strength tests were carried out with soil alone and soil mixed with different proportions of bagasse ash and ferric chloride, respectively. The different soil samples were prepared and tested for compressive strength with addition of ferric chloride and bagasse ash of varying proportions, respectively. Further, the soil samples were also tested for compressive strength with ferric chloride of varying proportions and bagasse ash corresponding to optimum percentage, respectively. Further, soil samples with optimum percentage of bagasse ash and ferric chloride were prepared and allowed for a curing period of 7 days and 14 days, respectively. The strength characteristics of the soil samples corresponding to different combinations are studied, and results are discussed in detail.
