Soil-Bentonite Backfill Properties. The most important property of SB backfill is a low permeability. Typically SB backfill has a permeability in the range of 10-6 to 10-8 cm/sec. Environmental projects often require a permeability less than 1 x 10-7 cm/sec, but a levee or dewatering project may require a permeability less than 1 x 10-6 cm/sec. Either value is achievable with the right mix of ...

Dec 05, 2017· Bentonite Slurry in civil engineering. Bentonite slurry is a combination of sodium bentonite and slurry. A slurry is a thin sloppy mud or cement or, in extended use, any fluid mixture of a pulverized solid with water, often used as a convenient way of handling solids in bulk. This combination is frequently utilized to form a solid protective barrier in the ground.
The recognition of bentonite as a vital construction element is still in its latent stage, since a hefty percentage of foundations and other civil engineering activities are still carried out without using bentonite and are incurring much higher expenditure through use of cast iron of steel liners.
