Bio-mediated ternary stabilization of an expansive clay matrix using waste eggshell powder, xanthan gum, and cotton fibers: Mechanical behavior, swelling control, and microstructural evolution

Expansive clay soils utilized in compressed earthen construction often exhibit low strength, severe volumetric swelling, and high moisture sensitivity, limiting their structural utility in sustainable building practices. Although conventional stabilizers such as cement and lime i...
