Uses Of Bentonite In Construction Bentonite Slurry In

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.

Bentonite Application Of Bentonite Slurry In Civil

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.
