Applications of Steel Slag

• Environmental Remediation: It has found use as a barrier material remedy for waste sites where heavy metals tend to leach into the surrounding environment.
  • Steel slag forces the heavy metals to drop out of solution in water run off because of its high oxide mineral content.
  • It has been used successfully to treat acidic water discharges from abandoned mines.
• It can replace coarse aggregate due to a higher impact and crushing strength, and better anti-skid capacity.
