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...
Rammed earth blocks (REBs) are attracting renewed attention as sustainable building materials due to their low embodied energy and use of locally sourced soil, yet their limited tensile strength and moisture sensitivity restrict wider structural applications. This study investigates a dual enhancement approach, combini...
This study investigates the potential use of industrial grits waste, both alone and in combination with Portland cement, as a sustainable stabilizing agent for lateritic soils. Grits, a by-product of the pulp and paper industry with a high calcium oxide content, was characterized using laser granulometry and thermograv...
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...
Enzyme-induced carbonate precipitation (EICP) is an innovative soil stabilization method, though its performance can be limited by insufficient nucleation sites and uneven calcite distribution. This study investigates the use of coal-derived char as an additive in EICP-treated sodium bentonite-sand mixtures to improve...
