The use and influence of bentonite in bored pile construction

This guide explains what bentonite is, how it works, and indicates how construction techniques could, in practice, have significant influence over the final behaviour of a load bearing unit. The introduction deals with a variety of subjects such as the extraction of bentonite from natural deposits, its structure, the stabilising action of the slurry, the effects of suspension contamination and the effects of bentonite on the bond between steel and concrete.
