X-Ray Diffraction on a Mixture of Black Cotton Soil & Pond Ash

The black cotton soil is a troublesome expansive soil that causes numerous issues in the construction of structures built on it. It has a swollen and impervious appearance, as well as weak geotechnical subgrade properties. The aim of this study is to find a way to improve the various geotechnical properties of black cotton soil and pond ash. This study looks at how to enhance the engineering properties of black cotton soil with varying amounts of pond ash. In this study, pond ash is mixed in black cotton soil in proportions ranging from 0% to 50%. Testing is often used to assess engineering parameters. The Atterberg limits were used to investigate the engineering properties of black cotton soil with various percentages of pond ash. (Liquid Limit, Plastic Limit, and Plasticity Index), standard proctor test, differential free swelling index, swelling pressure and wet sieve analysis tests are conducted.
