If the trenches or borings are filled with bentonite slurry (in its liquid state), the slurry then converts to its gel state, thus supporting the walls of the trench or boring. To install casing in the boring or prefabricated concrete structures such a pipe in a slurry filled trench, the slurry need only be .

To investigate the potential use of Bentonite to evaluate its impact on various strength of ordinary Portland Concrete (OPC). It was accomplished to raise cement concrete by partially replaced of cement. An OPC batch, properly mix designed was prime; aiming at strength admixtures was also introduced to attain high workability. Normal compressive testing was performed for this purpose and the ...
