Engineering characteristics of compacted sand-bentonite mixtures
Sand-clay mixtures are commonly used as a liner/barrier material in various engineering applications, such as construction of hydraulic and waste containments. Permeability, compressibility and strength are important properties of sand-clay mixtures and are often required for the design of the …

Considerations of mineralogy and permeability testing of selected Sand/Bentonite mixes
… behaviour and chemical performance of selected Sand/Bentonite mixes to be used in the context of an environmentally inert landfill liner. Numerous test series in the laboratory focused on the permeability as a consequence of the physio-chemical characteristics of the selected mixes of two South …

Limiting membrane and diffusion behavior of a compacted sand-bentonite mixture for hydraulic and chemical containment
Sodium-bentonite (Na-bentonite) commonly is used either as an additive component or as the sole component of engineered barriers used for waste containment applications, because the tendency of Na-bentonite to exhibit high swell can result in the restriction of advective and diffusive contaminant …

Deep Energy Foundations: Geotechnical Challenges and Design Considerations
… The hole is then backfilled with a mixture of sand, bentonite and/or cement. The loop is connected to a geothermal heat pump and the fluid inside the loop is circulated. The heat energy is fed into the ground for cooling in the summer and withdrawn from the ground for heating in the winter. …
