This work produced glass foams from soda-lime bottles, bentonite, and alumina by the replica method. Compositions with different contents of bentonite (5, 10, 15, 20 wt%) were prepared heat-treated at 800 °C. In alumina-added compositions, 50 wt% was replaced alumina. The influences content (binder) addition evaluated through physical-mechanical properties. results showed that did not promote a...
