To this end, three 1.2-m diameter and 27-m long bored piles were constructed, two of which were excavated under polymer fluids [i.e., (1) Pile P1, and (2) Pile P2] and one under bentonite (Pile B1). The Marsh funnel viscosity of the support fluids, measured prior to use, were 70, 69, and 34 s for Piles P1, P2, and B1 respectively.

The value of cohesion, c for the case of bentonite layer at pile–clay interface is found to be about 75% less, compared to the case when the effect of bentonite layer was not considered. Similarly, it was observed that with the presence of bentonite slurry, frictional resistance decreased by 24–56% in case of sand–concrete interface, …

By adding Sulphur bentonite to the Soil, it reduces the PH to 6.5 – 7.0 and allows primary nutrients to pass through the soil. Thus, Primary nutrients are available to the Plants. It releases Sulphur slowly and hence the Sulphur is available to the plants for the entire crop period. It gives strength to the plants and thickens the branches.
