Extensive subgrades present severe structural challenges globally due to their inherent tendency to swell upon moisture intake and undergo severe volumetric contraction during dry seasons, causing structural distortion and excessive rehabilitation expenses. This experimental investigation appraises the stabilization pe...
This study assessed the performance of Ordinary Portland Cement (OPC) in stabilizing crude oil-contaminated silty clay soil with special focus on the improvement of the geotechnical and microstructural properties. Geotechnical tests were conducted on soil samples contaminated with crude oil at concentrations up to 20%...
Expansive soils, featuring severe swelling-shrinkage behavior and low bearing capacity, pose persistent challenges to geotechnical infrastructure. As a promising alternative to lime and cement stabilizers, calcium carbide residue-rice husk ash (CCR-RHA) blends have been widely investigated, but existing studies focus m...
