Critical Review for Utilization of Blast Furnace Slag in Geotechnical Application

In the present state, the utilization of various waste materials in a different geotechnical application is increase manifold. All the waste materials possess different characteristics depending upon its raw materials and processing techniques. Utilization of these waste materials needs greater concern of its properties and compatibility with parent material. Out of many waste materials available, blast furnace slag is one of them. Blast furnace slags are by-products of metallurgical processes. It is glassy material, vesicular textures, typically with sand-to-gravel-size particles can be converted into powder form as well as particular desire size particles. In this paper, critical review has been made for the utilization of this blast furnace slag in various geotechnical applications depending upon the situation in weak and problematic soil condition. The review of this nature will lead the path in which various experimental program can be perform to find out the solution of different on-site geotechnical problems. The blast furnace slag has versatile characteristics by which it can compatible with all types of soil and provide appropriate solution for any soil stabilization process. Based on the review findings, some suggestion can be made for various geotechnical problems by utilizing this underutilized material, especially in Indian context. This paper ultimately become source for one of the interesting areas of research in which utilization of blast furnace slag in geotechnical application will have technical advantage as well as beneficial in protection and perseverance of natural resources.
