Use of Granular Blast Furnace Slag in Embankment Construction

Huge quantities of blast furnace slag, is being generated in the steel plants during the extraction of iron from iron ores, and they are normally dumped in and around the plant occupying a large land area apart from causing significant environmental problems. Granular Blast Furnace Slag (GBFS) resembles to cohesion less granular material and is observed to contain mostly the sand-size particles. Therefore, the industrial wastes like Granular Blast Furnace Slag (GBFS) if used as a substitute to good quality borrow soils for base/ sub-base course in flexible pavements or as an embankment material, it may significantly decrease the construction cost apart from increasing the sustainable development. This study is carried out to utilize the slag in embankment construction. Being cohesion less material, it is mixed with local soil collect from Suvali near Eassar steel Ltd. As, the embankment/subgrade having high strength, can resist to deformation and increase the stability of the pavement. If the parent soil does not have good engineering properties can achieved with the use of additives/stabilizer. This additives/stabilizer is mixed with the soil materials to get desired improvement. This study focus on mechanical stabilization of parent soil (CH type) using GBFS. The CBR tests are conducted to check the four day soak strength of the soil mixed with the GBFS in different range (10 %, 15 % and 20 % by mass). The results of these tests are comparing with soil stabilized with lime (3, 4 and 5 % by mass) and cement (0.5, 1 and 1.5 % by mass) with different proportion.
