Use of Blast Furnace Slag Aggregate in Concrete

Use of Blast Furnace Slag Aggregate in Concrete

The use of blast furnace slag aggregates in concrete by replacing natural aggregates is a most promising concept because its impact strength is more than the natural aggregate. Steel slag aggregates are already being used as aggregates in asphalt paving road mixes due to their mechanical strength, stiffness, porosity, wear resistance and water absorption capacity. C 1.1.
