Foam Glass From Cullet

This paper demonstrates the possibility of using recycled glass to obtain foam glasses as products possessing some added value. SiC powder, or fly ashes, were used as foaming agents, the last being an industrial waste material itself. The control of the cellular structure and therefore the tailoring of the expected final material properties was achieved by varying the processing parameters. Compressive strength of the final foam glasses up to 3.3 MPa were obtained. In the case of fly ashes from fuel oil as foaming agent it was verified that the obtained products are chemically inert.
