Abstract

UN METODO Y UNA MEZCLA PARA ESTABILIZAR QUIMICAMENTE POLVO DE HORNO DE ARCO ELECTRICO (EAFD) POR ARRASTRE DE LOS METALES INHERENTES EN EL EAFD DENTRO DE UN PRODUCTO ENDURECIDO EN FORMA DE CEMENTO PROCEDENTE DE LA MEZCLA. EL METODO INCLUYE EL APROVECHAMIENTO DE LAS CARACTERISTICAS PUZOLANICAS DEL EAFD Y LA FORMACION DE UNA MEZCLA DE EAFD CON SUFICIENTE AGUA Y CAL, LA QUE SEA NECESARIA, Y A CONTINUACION PERMITIENDO A LA MEZCLA QUE REACCIONE PARA FORMAR UN PRODUCTO ENDURECIDO EN FORMA DE CEMENTO. EL PRODUCTO ENDURECIDO TIENE CONCENTRACIONES DE FILTRADO ACEPTABLES, PERMEABILIDAD CARACTERISTICA Y RESISTENCIA A LA COMPRESION ILIMITADA.
