A Review on Behaviour of Beam Column Joint Using EAF Steel Slag Concrete
The amount of industrial waste generated and the overexploitation of quarries worldwide are becoming one of the serious environmental problem. Electric Arc Furnace (EAF) steel slag is currently used for asphalt concrete pavements in many countries but huge quantities of this material are still landfilled. Reusing the slag as recycled material in the construction industry not only helps in the reduction of the amount of waste disposed off but can also bring down the consumption of natural aggregates. EAF slag is the secondary product of the steel production process and is procured after the separation of molten steel from impurities. In this review paper, the impact of using EAF concrete on the structural behavior of internal beam-column joints and also the resisting mechanism of these joints are studied. A parametric study on the structural performance of EAF concrete compared to conventional concrete in terms of the load-carrying capacity, energy dissipation and strength attained by the joint in failure condition is made.
