This article presents a comprehensive study on the efficacy of xanthan gum (XG) biopolymer as green construction material in treating problematic expansive subgrade. The soil was treated with various concentrations XG (0, 0.5, 1.0, 1.5, 2.0, and 5.0%) considering long-term aging period 4, 7, 14, 28, 60 365 days). results showed reduction plasticity at higher increase content. At 1.5% content unconfined compressive strength, elastic modulus, resilient unsoaked soaked CBR values were notably increased by 5–10 orders magnitude regarded optimum. Meanwhile, microstructural studies coupled elemental analysis highlight bridging particles stiff XG-hydrogel formation that contributes to strength development. Overall, XG-treatment exhibits an economical sustainable solution for treatment

Abstract This study comprehensively explores the compaction and compressibility characteristics of snail shell ash (SSA) ground-granulated blast-furnace slag (GBFS) in stabilizing local bentonite for landfill baseliner applications. The untreated soil, with a liquid limit 65%, plastic 35%, plasticity index 30%, exhibited optimal at moisture content 32% maximum dry density 1423 kg/m 3 . SSA revealed dominant presence 91.551 wt% CaO, while GBFS contained substantial 53.023 SiO 2 Treated samples 20% 5% highest (1561 ) (13%), surpassing other mixtures. 15% SSA-treated sample demonstrated superior strength enhancement, reaching an unconfined compressive 272.61 kPa over 28 days, 10% GBFS-treated achieved 229.95 kPa. combination shear (49 kPa) elastic modulus (142 MPa), showcasing robust mechanical properties. Additionally, displayed favourable hydraulic conductivity (5.57 × 10 –8 cm/s), outperforming Notably, permeability test, critical aspect study, was meticulously conducted triplicate, ensuring reliability reproducibility reported values. showed reduced compared to control exhibiting more consistent response applied pressures. Scanning Electron Microscopy analysis composition changes mixture, suggesting its potential as effective base liner systems. In conclusion, properties conductivity, presenting promising choice
