Research Objectives and Key Topics

This research aims to evaluate the effectiveness of using brick dust and cement as stabilizing agents for soft clayey soil collected from Manikdi, Dhaka. The study focuses on determining whether the addition of these materials in specific mix proportions improves the soil's engineering performance, particularly its strength, plasticity, and specific gravity characteristics.

• Evaluation of cement and brick dust as soil stabilization agents.
• Experimental analysis of soil properties including Atterberg limits and specific gravity.
• Investigation of soil strength enhancement via unconfined compression testing.
• Comparative study of natural soil versus mixed soil samples (Cement: Brick Dust: Soil).
• Development of geotechnical data for potential site construction improvements.
