RESEARCH ON THE APPLICATION OF FERROMANGANESE-SILICON SLAG MICROPOWDER IN THE BUILDING MATERIALS INDUSTRY
Ferromanganese-silicon slag is an industrial waste generated during the production of ferromanganese-silicon,with an annual output of about 10 million tons.The disposal methods of the ferromanganese-silicon slag are closely relat-ed to the sustainable and healthy development of enterprises and their impact on the environment.The waste resource uti-lization of ferromanganese-silicon slag becomes particularly important.The article mainly explores the influence of differ-ent addition mixed by and between different fineness slag micropowder(that prepared by pre-treatment of ferromanga-nese-silicon slag and then separated inert substances)and different dosage of activator independently developed by JITIE on the activity coefficient of slag micropowder.The experimental results show that when the amount of activator added is 5%and the specific surface area of slag micropowder is 650～700 m2/kg,the activity index of slag micropowder can reach and even be higher than the S95 or S105 index values in GB/T 18046-2017.
