... and overlying strata is an important consideration in safety assessment. To examine the impact of material variability, British Geological Survey developed a methodology to manufacture ‘synthetic rock’ samples from mixtures of clay, sand, and silt. Diffusion experiments were conducted on these, and natural...

...Fatih Yıldız; Mustafa Vekli This study investigates the effects of waste hemp stalks on expansive clay soils. Hemp, a biodegradable and sustainable material, was used at 5%, 7.5%, and 10% by dry weight to stabilise a clay mixture (70% kaolin, 30% bentonite). Laboratory tests, including Atterberg...

... performance. In this study, the deformation and transport responses of clayey soils under thermo–mechanical–chemical ( TMC ) coupling are investigated using a previously benchmarked one-dimensional coupled numerical model. Soil settlement behaviour and clay liner performance are analysed under single (T, M...

...Séverine Levasseur; Jean Talandier; Paul Marschall In many countries, geological disposal facility is considered as an option for the long-term management of radioactive waste. In the French, Swiss, and Belgian concepts, clays have been selected as suitable host formations. Considerable amounts...

...Fatih Polat; Tuğçe Özdamar Kul; A. Hakan Ören Bentonite is a critical component of geosynthetic clay liners (GCLs) because of its low hydraulic conductivity. However, bentonite can migrate within the GCL roll while transporting and installing the GCL . Thus, the bentonite mass per unit area...

... results show that the lime-treated soil is sensitive to exposure to ambient moisture. Nevertheless, the lime-treated soil still retains a much higher UCS compared with the natural soil. Wei et al. (2022) analysed the influence of 15 F-T cycles on stabilised silty clay through triaxial tests...

... as the biochar-induced nucleation (MICP-BIN) method for reinforcing clay soil. Corn stover biochar was employed as an auxiliary material, mixed with dry clay powder, and subsequently reinforced using the MICP technique. Direct shear tests, drying experiments, X-ray diffraction, and scanning electron microscopy...
