Abstract

Lime Kiln Dust (LKD) is the by-product of Quick Lime (QL) production which is mostly disposed off into landfills globally. Therefore, LKD needs to be reused to reduce environmental problems and promote sustainability. This paper presents preliminary investigations on the use of LKD as a cementitious material in mortar. LKD was added to mortar mixtures to study its effect on the strength by replacing ordinary Portland cement (OPC) up to 60% by weight with LKD. Experimental results on physical and engineering properties, and compressive strengths of mortar samples containing LKD are reported. Results indicated that the initial and final setting time of the LKD mortar tested ranged from 1.08 to 2.3h and 4.58 to 5.8h respectively, and the strength values from 36.35 to 68.08MPa for 90 days strength. Furthermore, addition of LKD reduced the strength of the mortar but with a faster setting time. It can be concluded that there is a good potential for the use of LKD as a cementitious material with accelerated hydration rates.
