Abstract

The Report 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 of the Report also deals with a variety of subjects; the extraction of bentonite from natural earth deposits, its structure, the stabilising action of the slurry, the effects of suspension contamination, filter cake formation, the displacement of suspension from a borehole by concrete, the technique of placing concrete by tremie, the selection of appropriate concrete mixes for this type of work, and the effects of bentonite on the bond between steel and concrete.
