Study on Seepage and Strength Characteristics of Black Cotton Soil Admixed with Copper Slag
The usage of industrial by-products in construction has been common globally adopted due to shortage of natural materials. Copper slag is one such by-product which is available from the copper industry in India. Their disposal and recycling have gained prominence as usage of such materials serves the sustainability goals of the nation, whereas black cotton soil is well known for highly expansive nature, low permeability, and poor strength. Many researchers have worked on reinforcing black cotton soil to check its ability to serve as subgrade material, but enhancement of drainage characteristics of black cotton soil requires more attention. Present study is to observe the change in permeability and strength characteristics of black cotton soil by adding varying percentages of copper slag and to obtain to the optimum percentage of copper slag. Permeability tests, CBR tests, and direct shear tests were conducted for black cotton soil along with copper slag by varying the percentages of copper slag as 20%, 30%, 40%, and 50%. Permeability has increased subsequently with the increase in percentage of copper slag in black cotton soil and at 50% of copper slag content permeability reached to as that of medium sand and CBR value increased by four times. The optimal percentage of copper slag from the study is observed as 30% in addition to the improved shear strength.
