Abstract

Procedimiento para la estabilización de piedra de cemento, que se forma a partir de aglutinantes ricos en aluminatos por fraguado con agua, caracterizado porque se mezclan el aglutinante rico en aluminatos y residuos de sulfito de calcio procedentes de la purificación de gases de escape de instalaciones de combustión, en una cantidad de al menos 0,2% en peso, calculado como CaSO3 y referido a aglutinante rico en aluminatos, con la cantidad de agua necesaria para la hidratación normal, y se deja que fragüe la mezcla resultante para producir piedra de cemento.
