Characterization of Expansive Soil and Lignosulphonate Stabilized Soil by SEM and XRD

The objective of the work is to provide the outcomes of Scanning Electron Microscope (SEM) and X-ray diffraction (XRD) tests and their investigations on natural, lime-treated clay and lignosulphonate-treated clay to estimate the percentage of bonding compounds after soil stabilization. XRD tests were performed on natural soil and soil-treated mixtures of 3% lignosulphonate by mass. These mixes were tested at a distinct period of curing of 28 days and tested as the sample before the addition of lignosulphonate and after treatment of soil with lignosulphonate. Strength Improvement has been observed due to the increase in Quartz mineral which is SiO2 in nature.
