Abstract

In the first part of this study, fly ash has been used as a main component in developing glass compositions which are cellulated through carbonization and oxidation processes. The resulting foam glasses have highly uniform closed pore structure and negligible water permeability with densities ranging from 140 kg/m3 to >800 kg/m3. Foam glasses with open pore structure have also been produced and characterized. In the second part, mechanical and thermal properties are discussed. These include the stressing rate effect on the fracture strength in compressive and flexural loading for different densities. Variations of thermal conductivity and overall strength with density and pore size are also described.
