Experimental Studing on the Stability of Sandy Slopes Stabilized With Cement Kiln Dust Under the Effect of Strip Footings

Abstract

In this paper, presents of experimental tests carried out on physical and chemical properties of cement kiln dust. Cement kiln dust is considered a one of waste which produced in a local cement production plant production plant Portland cement manufacturing in Assuit Cement Company-Egypt. The main aim of this study is to examine some factors that influence the performance of a strip footing resting on a sandy slope by the utilization with CKD. This study aims also at establishing relationships between the bearing capacity and the CKD percentage and forming a database for future development of a rational design method. The angle of the slope was taken equal to (42o). Laboratory tests on small scale model were carried out. The experimental model was simulated by the finite element method (FEM) using the computer program PLAXIS. The verification of the numerical results by the corresponding experimental results has been done to emphasis the accuracy of the parameters used in the numerical analysis.
