Cathode Ray Tube (CRT) waste glasses produced from dismantling TV sets were used to prepare glass foams by a simple and economic processing route, consisting of a direct sintering process of mixtures of CRT waste as glass powder with different foaming agents (coal fly ash and limestone quarrying residues). The influence of firing temperature, amount and type of foaming agent on the apparent density, pore size distribution and compressive strength have been studied. The aim of the work was to investigate the possibility to obtain glass foams using exclusively wastes as starting materials, and therefore replacing the conventional raw materials. © 2015 Taylor & Francis Group, London.
