PREPARATION AND MECHANICAL PROPERTIES OF DIOLMER GROUP
A study was conducted on the preparation of an ecological pavement brick using steel slag and red mud as partial substitutes for cement,molding sand as fine aggregate,and construction waste as coarse aggregate.Through chemical composition analysis(XRF),scanning electron microscopy(SEM),and mechanical performance testing,the reaction mechanism of the alkaline activation system of steel slag red mud based geopolymer was the-oretically studied using molding sand as the alkaline activator,and mechanical performance testing was conducted.The results indicate that as the curing time of the specimens increases,the mechanical properties of ecological pave-ment bricks also improve.When the sand sand sand ratio is 37%and the steel slag red mud ratio is 3∶2,the ecolog-ical pavement brick prepared has the best mechanical properties.
