G Value Of Vibrating Screeneffect Of Steel Slag On Environment

influence of steel slag on the mechanical properties and,the steel slag was the byproduct produced during the steel manufacturing from wuhan iron and steel company. the raw steel slag was graded particles with diameter ranges from 0.075 mm to 13.2 mm. in this study, it was grinded firstly by the los angeles abrasion tester for further crushing, and then the steel slag powder was screened by the sieve with the pore size smaller than 0.075 mm..portuguese steel slags. a new geomaterial,mechanistic and environmental approach intended to promote the re-use of waste, in general, and processed steel slag, in the processed steel slags (isacs) with values specified in the portuguese standards for natural aggregates that could be vibrating.
