Effect of bentonite, Kaolin and fly ash percentages on mechanical response of Zemmouri sand
Effect of bentonite, Kaolin and fly ash percentages on mechanical response of Zemmouri sand
The main objective of this experimental work is to study the effect on the shear strength of Zemmouri sand mixed with three types of fine content (fly ash, Kaolin and bentonite). The range of fine content varying from FA=0% to FA=30% using the direct shear box. The specimens were reconstituted at the lab by dry pluviation method with a medium dense initial relative density (Dr=55%) and which were subjected to three normal stresses of 100, 200 and 300kPa. The results found indicate that adding fines induces a small variation in the mechanical responses for the three types of fines considered. Therefore, we concluded that for Zemmouri Sand there is no improvement in terms of mechanical response.
