Sustainable utilization of cement kiln dust and GGBS in the development of eco-friendly concrete composite

Abstract

Concrete is an unavoidable element in modern construction. During concrete production enormous amount of CO2 is emitted which results in global warming. From the point of view of environmental protection, sustainable concrete production should be focused on. An eco-friendly solution to lessen the impact on the environment has been briefed in this article. Ground Granulated Blast furnace Slag (GGBS) and cement kiln dust have been partially replaced with cement. The strength and durability properties of GGBS and cement kiln dust-incorporated concrete were evaluated and presented. The optimal substitution percentage of GGBS and cement kiln dust was reckoned as 15% and 12% respectively. The test results fortified that the replacement of GGBS and cement kiln dust for cement in concrete becomes an eco-friendly solution from the point of view of quality and sustainability.
