Can We Use Electric Arc Furnace Slag In Concrete

Use of Steel Slag Aggregate in Pavements Report

Electric arc furnace slag is a byproduct of the production of steel in an electric arc furnace. In electric arc furnaces the charge materials (scrap iron and steel) are loaded into the furnace and directly exposed to electric terminals. The current passing through the terminals creates an electric arc that melts the charge materials.
