STABILIGATION TECHNOLOGY OF FE-NI SLAG FOR FINE PEBBLE AND GRAVEL USING BLAST FURNACE SLAG AND COAL FLY ASH

摘要

PURPOSE: A stabilizing method of ferronickel slag using water-cooled blast furnace slag and coal ash is provided to reduce the alkali aggregate reaction generated when using the ferronickel slag as fine aggregate. CONSTITUTION: A stabilizing method of ferronickel slag for fine aggregate is a method using cement, blast furnace slag, and coal ash for controlling an alkali aggregate reaction for using the ferronickel slag including 55~60wt% of SiO2, 32~37wt% of MgO, 1~2wt% of CaO, 2~5wt% of Fe2O3, and 1~2wt% of Al2O3, as the fine aggregate.
