Strength Characteristics of Expansive Soils Using Epoxy resin and Silty Soil

Improving the properties of soil by stabilization is considered as a means of fulfilling design criteria. Stabilization is usually performed to improve material properties of soil such as strength and stiffness. The use of new materials for soil strengthening is crucial for geotechnical engineering, especially in foundation construction. Experiments were conducted using resins with different epoxy resin polymer-to-water (ER/W) ratios. The results show that by increasing the Epoxy resin polymer in the black cotton soil is increasing its shear strength. The Epoxy resin and hardener in 10.1 ratio was used. In this study deal with the obtaining the unconfined compressive strength values and Tri axial test values by fixing 5 % Epoxy resin polymer and % varying of Silt Content (10 %, 20 %, 30 %, 40 % and 50 %). The results indicate that the epoxy resins improve the mechanical properties of soil significantly, and the Silt Content is increasing the shear strength and angle of internal friction, cohesion changes significantly, if successfully grouted into a formation, the resins could provide a suitable solution for the stabilization of foundation material.
