PPT-Performance of Slag Pavements

Prepared by Peter Rufford P E E C E Introduction Steel Furnace Slag is a waste product from steel making Has been used as a road base material in areas close to the steel making operations. For one large scale blast furnace production rate of melted slag at about 1500 is 100 150thour Solidified by natural cooling in atmosphere or rapid cooling by water Heat recovery has not yet been done Potential of melted slag as heat source Melted 6 Slag cement reduces concrete permeability Low permeability in reinforced concrete is important to maintain structural integrity Permeability is a measure of how easy it is for water air and other substances such as chloride ions to enter concrete BLAST FURNACE SLAG & SLAG CEMENT GRANULATED BLAST FURNACE SLAG Blast Furnace Slag is an industrial by - product for production of pig iron from iron ore in blast furnaces.
