Abstract

In bored piling construction, drilling is the method in which bore holes are created for the placement of piles. the mixture of bentonite and water is used as the drilling fluid during the drilling process so as to stabilize the wall of soil in the bore holes. Bentonite is known as an additive that can be used to improve soil stability. This paper studied the effect of bentonite on soil strength and viscosity that was sampled from the project site. The direct sher test was used to determine the maximum shear strength of the different test specimens, while a cone viscometer was used to determine the soil viscosity. The sudy was limited to three different bentonite I mixtures. Results showed that incorporation of bentonite increased the shear strength data and led to increase in viscosity of soil specimens. Lastly, using the shear strength data and Unified Soil Classification System, the type of soil taken from the project site was determined to be silty soil.
