    The ACBF slag aggregates under consideration function as reactive base/subbase layers beneath porous pavement installations. Mineralogically, the ACBF slag was dominated by akermanite (Ca 2 MgSi 2 O 7) and gehlenite (Ca 2 Al 2 SiO 7), with a considerable amorphous phase as determined by quantitative X-ray diffraction (QXRD). ACBF slag samples taken from three different northern Indiana steel mills

  • Cooled Slag - an overview ScienceDirect Topics

    Immediately after being discharged from the blast furnace, the molten blast furnace slag is dumped into cooling pits for air-cooling before further processing for slag products. When the slag undergoes air-cooling in the pit, stratification of the layers resulting from pouring hot molten slag over partially cooled slag, causes cracking so that upon further cooling it can be readily picked up with power shovels.
