Effects of chemical solutions on the hydromechanical behavior of a laterite/bentonite mixture used as an engineered barrier
TL;DR: In this paper, the feasibility of employing a laterite/bentonite mixture as a vertical barrier in landfills, tailings ponds, or sites contaminated by heavy metals was explored.
Journal ArticleDOI
Assessment of the influence of copper and zinc on the microstructural parameters and hydraulic conductivity of bentonites on the basis of SEM tests.
TL;DR: The results showed that the behavior of bentonites saturated with Cu2+ and Zn2+ ions differed, and the authors believe that the empirical formulas of the hydraulic conductivity of the clays saturated with potentially toxic metals should be based on the selected clay parameters dependent upon the nature of the ion.
Journal ArticleDOI
Study on the microscale structure and anti-seepage properties of plastic concrete for cut-off walls modified with silica fume: Experiment and modelling
TL;DR: In this paper, a modified plastic concrete cut-off wall was synthesized using different mass ratios of silica fume (0,21.3%) and constant cement content (8%) based on the conventional soil-bentonite cutoff wall.
Journal ArticleDOI
The effects of potentially toxic metals (copper and zinc) on selected physical and physico-chemical properties of bentonites.
TL;DR: It was observed that the significance of the influence of Cu2+ and Zn2+ ions on specific clay properties differed, which indicates different behavior of these metals in the clay-water system.
Journal ArticleDOI
Insight into barrier mechanism of fly ash-bentonite blocking wall for lead pollution in groundwater
TL;DR: In this article, the service life of the fly ash-bentonite mixture, which is shown to be superior to other bentonite mixtures, including silt, loess-silt, and kaolin, was determined.
