Sustainable stabilization of silty sand using Terrazyme: effects on mechanical and hydraulic properties

Sustainable Stabilization of Lateritic Soils Using Industrial Residue Grits: Mechanical and Microstructural Insights

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...

Experimental study on the engineering performance of LSP stabilized expansive soil under cyclic drying-wetting condition

Conventional binders to treat expansive soil commonly present challenges of high cost and significant environmental burdens. To address these limitations, this study proposes an environmentally sustainable binder termed LSP (lime-sodium silicate amended phosphogypsum) based on the valorization of phosphogypsum (PG). Sy...

Microstructural and Geotechnical Evaluation of Cement-Stabilized Crude Oil-Contaminated Silty Clay

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%...

Investigation of the Factors Affecting the Unconfined Compressive Strength (UCS) of the Subgrade Soil Stabilized with Copolymers

Laboratory Study on the Geotechnical Behaviour of Expansive Soil Treated with Coconut Husk Ash and Silica Fume

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...

Studies on the Mechanical Properties and Carbon Sequestration Potential of Geosynthetic-Reinforced Soil Incorporating Biochar

This study evaluates the feasibility of using biochar-amended soil (BAS) as a sustainable backfill material in geosynthetic-reinforced earth structures, considering both mechanical performance and carbon sequestration potential. Laboratory tests, including standard Proctor compaction and consolidated drained triaxial t...
