Improving the stability of bentonite slurry using gellan gum biopolymer

The distinctive properties of bentonite, including hydration, swelling, water absorption, ion adsorption, high viscosity, and thixotropy make it a valuable material for many applications in geotechnical engineering such as hydraulic barriers, drilling slurry, and landfill liners. This study introduces gellan gum as a friendly environmental additive that improves bentonite slurry stability when bentonite is used for soil stabilization during excavation in emergency response.
