Foam glass-ceramics are porous material with the desired strength. In this work, steel slag was mixed with soda lime glass in (20, 40, 50, 60, 70 wt. %,denoted by SG20,SG40,SG50,SG60,SG70) and 5 wt.% SiC. Giving to Hot stage microscopy images, glass-slag composite's contraction starts at 1050ºC. According to the SEM micrographs the tunnel-like pore porosity resulted from the decomposition of carbide phase were formed. The sizes of pors varies in 500 - 1000 μm range. More over by the 50 wt. % soda lime glass addition and sintering at 1200 ° C, the spherical porosity were formed and the size of the porosity were reduced to 50 μm in these composites. Also, by the the glassy phase increasing, the total porosity was increased to 80%, the density decreased to 0.8g / cm3in SG40. This composite as a porous material has 2 to 5 MPa bending strengths. Wollastonite phase was detected in these composite.
