In this study, humic acid-iron-columnar bentonite (HA-Fe-PILC) obtained after HA adsorption
on Fe-PILC was characterized by SEM, BET, XRD, zeta potential, FTIR, and XPS and reused …

Soil-bentonite (SB) cutoff walls have been extensively used as vertical engineering barriers
to control groundwater flow and subsurface contaminant migration. As the pollution …

The use of waste materials in the building industry is a major challenge for eco-efficient
construction. Brazil generates more than 3 million tons of waste foundry sand (WFS) …

Bentonite is commonly used as sealing material in seepage cut-off walls to minimize the
permeability of sandy soil. To further reduce permeability and stabilize the sand-bentonite …

Porous ecological concrete (PEC) consisted of coarse aggregate and hydrated
sulphoaluminate cement (SAC) covering on the aggregate is an excellent material for …

In some countries lacking sodium bentonite (NaB), polymer-modified calcium bentonite
(CaB) has attracted attention for its application in sand-bentonite slurry trench cutoff walls to …

Sand-bentonite slurry trench cutoff wall is one of the most common vertical barriers to retard
the migration of contaminants. This study aimed to explore the hydraulic and consolidation …

Modified calcium bentonite (Ca‐bentonite) is extensively used in engineered barrier
systems (EBSs) for municipal and industrial disposal sites due to its high swelling potential …

The soil-bentonite (SB) slurry-based barrier technology is successfully used to isolate the
heavy metal contaminants at sites. While the heavy metal-induced deterioration effects …

Groundwater barriers are extensively used for absorbing and blocking heavy-metal
contaminants in groundwater. Experiments were conducted to characterize and evaluate the …
