Utilisation of Cement Kiln Dust and Red Mud for Construction of Highway Embankments in Cohesion Less Soil

Abstract

Red mud is the waste product of the steel industry and Cement kiln dust is the waste product of the cement industry. Government of India has to acquire a large amount of land to dump this waste which proves to be very uneconomical and these both wastes has a lot of environmental hazards. In the areas of loose soil, the construction of pavement is not easy so, we decided to use Red mud and CKD mixture with the cohesion less soil. Tests have been done to classify the type of soil we use and various experiments have been done to ensure that the mixture of Red mud, CKD and cohesion less soil proves to be optimum and fit for the use of pavement construction. With the use of these waste products not only a large amount of land is saved from dumping but a good strength is obtained from the mix of waste products which is of no use.
