Geotechnical and Environmental Impacts of Steel Slag

Dec 04, 2014  Because of this chemical composition, slag can expand in humid environments, which could cause the heaving of pavements and uneven, rough and cracked pavement surfaces. This could result in millions of dollars in annual repair costs to rehabilitate the structures (Motz and Geiseler 2001, Juckes 2003, Rojas 2004, Deniz et al. 2009).
