  • The goal of this study was to find an application method of the waste soda-lime glass as the feed material for foamed glass by foaming of hydrated waste glass. The proper conditions for the foaming of hydrated waste glass were found to be: temperature of $92.5^{\circ}C$; reaction time of 10~20 min; particle size of -325 mesh as the unhydrated glass starting materials; and graphite weight to the hydrated glass ratio of 0.003 as the foaming agent. The resulting formed glass made from hydrated mixed waste glass under above mentioned conditions had the characteristics of density less than $0.2g/cm^3$ and thermal conductivity of $0.05kcal/mh^{\circ}C$.
