Use of Steel Slag in Subgrade Applications

In 2006 10-15 million metric ton of steel slag was generated in the U S Out of the total steel slag produced in the U S every year about 50-70% is used as aggregate for road and pavement construction and approximately 15-40% is stockpiled in steel plants and eventually landfilled at slag disposal sites Get price

The Characterization of Steel Slag by Alkali Activation

The ratio between steel slag and alkaline liquid was fixed at 3 31 for all mixtures Ambient curing (20℃ - 25℃) are used throughout the experiment Compressive strength shows the alkali-activated steel slag presented high strength at 14 days curing which is 21 56 MPa In comparison the alkali activated steel slag had better strength than 50/50 Fe/SS alkali-activated slag which only achieved 16 75 MPa Get price
