Stabilization characteristics of cement-kiln dust

This paper presents the results of laboratory study conducted to evaluate the engineering characteristics of cement-kiln dust collected from major cement plants in Saudi Arabia, consistency and strength of cohesive soil stabilized with lime/cement-kiln dust a by-product of a cement manufacturer plant in the city of Riyadh. It was found that variability in chemical composition and physical characteristics of collected cement-kiln dust samples is not very significant. It was also found that cement-kiln dust is a promising material in stabilization of cohesive soft soil. With the addition of a proper amount of stabilizer and by allowing the mixture to cure for a sufficient period of time, cement-kiln dust stabilization produced better improvement in consistency characteristics, strength and stiffness than lime stabilization.
