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

This article explores the novel application of Google Earth Engine (GEE) platform using inverse distance weighting (IDW) interpolation technique based on an improved version modified Shephard method for development specialized geotechnical soil maps (GSMs) mega-district Lahore. The study area was assessed at multiple depths in terms key properties. result depicts a predominance fine-grained shallow depth 3 m exhibiting low to moderate stiffness, consistency and activity along with few zones problematic adverse characteristics which require due attention. Whereas beyond exhibits higher bearing values, plasticity non-active soil. Besides, chemical content level within permissible limits except spots. comprehensive statistical evaluation performance indices indicates efficient GEE-based IDW algorithm yield significantly accurate maps.

Geotechnical Investigation of Gelatin Biopolymer on Cohesive Soils

Sustainability, Journal Year: 2023, Volume and Issue: 15(3), P. 2041 - 2041

Published: Jan. 20, 2023

Gelatin, a biopolymer derived from animal proteins, has been selected to stabilize three fine-grained soils by determining select index and engineering properties. Specimens for California Bearing Ratio (CBR) were tested using different curing methods, i.e., thermally cured at 60 °C, unsoaked, 7 days air-cured submerged specimens. The amount of gelatin added the soil ranged 0.5% 2% weight. sequence interaction between clays is as follows: (A) solution adsorbed agglomerated onto surface clay. (B) presence Al3+, Si4+, K+ ions on clay promotes blending connective linkages with negatively charged gelatin. (C) connection reinforcements harden period subsequent drying stabilized soils. (D) Drying gelatin–clay complex also establishes alternative bonding modes such van der Waals interactions ligand exchange. formed dry, rigid films after 72 h which responsible coating reinforcing particles. Thermal 1% addition yielded maximum CBR 91.42%, 141.1%, 122.3% high compressible clay, low silt, respectively, Unconfined Compressive Strength (UCS) 3968 kN/m2 UCS results revealed that brittle failure was predominant gelatin-amended 28 while shear observed treated 2 sample preparation.
