TITLE: IMPACT ON SHEAR STRENGTH OF BLACK COTTON SOIL MIXED WITH TERRASIL USING DIGITAL TRIAXIAL TESTS.
• DESCRIPTION: Studied the stabilization of expansive Black Cotton Soil by adding Terrasil in varying proportions. Conducted Atterberg’s limits, compaction, and triaxial shear tests to evaluate soil strength. Found that Terrasil reduced cohesion and improved internal friction angle, making the soil more stable and suitable for subgrade construction.
