Abstract
Self foaming cellular glass-ceramics were obtained by sintering mixtures of a basalt scoria and soda lime cullet for 15 min at 1050 and 1100 °C. The effect of polyvalent ions (Fe3 +/Fe2 +) on porosity (from 53 to 86 vol.%) and crystallization was studied for different mixtures subjected to different thermal treatments. Due to the range of mechanical strength values (crushing strength from 2 to 50 MPa) and total porosity achieved, these porous glass-ceramics could be applied as building materials, as lightweight aggregate for concrete or as lightweight panels.
