Abstract

A találmány tárgya eljárás cementgyártáshoz használható puccolán vagyhidraulitikus őrlőanyagok előállítására, mely bázisosan oxidáltsalakokból, különösen acélsalakokból indul ki, miután a salak fém-oxidtartalmának csökkentését fémfürdőben elvégzi a folyékony salakokbázikusságát savas javító anyagokkal, mint például kvarchomokkalés/vagy nagyolvasztósalakkal és/vagy SiO2 tartalmú javítóanyagokkal, aredukció előtt egy olyan értékre állítja be, mellyel a célsalakbázisossága (CaO/SiO2) 0,1-0,5 értékkel csökken.
