At the time of boring for Pile, the sides of the bore hole are subjected to numerous external forces and pressure like active earth pressure, hydrostatic pressure, pore Apressure, etc due to underground water. As a result the side of the bore become unstable and may collapse if the soil layers remain weak.
unnel excavation involves a certain risk of unexpected ground conditions. One of the risks is the chance of hitting large quantities of high pressure ground water. Smaller Tvolumes of ground water ingress canalso cause problems in a tunnel or its surroundings.
Bentonite is used for self-hardening mixtures Bemployed to build cut off walls, grouting mortars, and grouting. Finally bentonite waterproofing properties are best exploited in environmental engineering, to seal off soil infiltrations, and line the base of land-fills.
suspensions of bentonite in water are widely used across industries. The largest and best known use of bentonite suspension is as drilling mud. Due to its rheological Sproperties and thixotropy of aqueous suspensions, bentonite is used as a mud constituent for oil and water well drilling.
Bentonite is used as a bonding material in the preparation of moulding sand for the production of cast iron, steel, and non-ferrous casting. The unique properties of Bbentonite yield green sand moulds with good flowability, compactability, and thermal stability for the production of high quality castings
Bentonite swells several times of its mass, and then forms a strong water and chemical proof seal makes it an ideal, inexpensive, permanent, and easy to install liner. Also, Bsince it does not contain any chemicals, or additives, or anything toxic, bentonite is environmentally-friendly.
Bentonite clay is a Natural clay. It is pollution free and helps to maintain the green environment. The clay has high plasticity and can with-stand high temperature, i.e. Babout 15000C
Mahalaxmi Minerals Grade Bentonite powder can be used for cat litter as it has excellent swelling properties enabling absorption of refuse by forming clumps.
