Effect of Blast Furnace Slag and Ilmenite Sludge on Lateritic Soil for Geotechnical Applications

Protection of the environment from hazardous materials from industrial waste generation and disposal is a major concern in today’s world. Disposal of this waste in open areas is not environment-friendly solution, and rather it can be used in geotechnical application in large scale. This paper investigates the applicability of blast furnace slag (BFS), ilmenite sludge and quarry dust admixed with local lateritic soil mixtures as a replacement for conventional pavement material. A series of combinations from these materials was made, and test comprising California bearing ratio (CBR)-soaked, compaction and unconfined compressive strength (UCC) was conducted on these samples. The results demonstrate there was an increase in the strength properties and CBR values by adding various percentages of industrial waste with lateritic soil.
