Foaming geopolymers (light-weight porous inorganic materials) were successfully synthesized by alkali activator of mixed color waste glass powder without/with pure graphite powder (0.1 wt%) and dry intercalated graphite powder(0.1 wt%) as foaming agents; the specimens were thermally treated at 500,600,700 and 800°C for 1hour. An important volume increase was recorded (-11.8-240.68%), (68.25-146.64%) and (43.79-968.54%) for MG-N5, MGG-N5 and MGIG-N5 respectively after thermal treatment. A sharp increase in volume (important swelling) and shape deformation was recorded for the specimens with intercalated graphite (MGIGN5 pastes) at temperature 600°C. The microstructure and mechanical properties of these materials were also studied. The foaming geopolymers containing glass and graphite powder (G or IG) which were obtained from this work are strong candidates mostly for the applications demanding thermal insulation with favorable combination of light weight, porosity, mechanical strength and performance to produce construction materials.
