Abstract

La presente invención se refiere a procedimiento para el espumado de cenizas volátiles caracterizado porque se mezcla a las cenizas volátiles nitrito de silicio o carburo de silicio y sales alcalinas disueltas en agua y la mezcla se espuma a la temperatura de ablandamiento de las cenizas volátiles.The present invention relates to a process for foaming fly ash characterized in that silicon nitrite or silicon carbide and alkaline salts dissolved in water are mixed with the fly ash and the mixture is foamed at the softening temperature of the fly ash.
