INFLUENCE OF NA2O/AL2O3 AND SIO2/AL2O3 RATIOS ON THE IMMOBILIZATION OF PB FROM ELECTRIC ARC FURNACE INTO THE FLY ASH BASED GEOPOLYMERS

Influence of Na2O/Al2O3 and SiO2/Al2O3 ratios on the immobilization of Pb from electric arc furnace into the fly ash based geopolymers

Electric arc furnace dust (EAFD) is by-product of iron and steel scrap remelting in electric arc furnace.This waste is classified as a hazardous material due to the leaching of heavy metals into the environment.Geopolymeryzation of fly ash into construction materials called - geopolymer is a considering as a possible way of immobilization majicontr
