Original Abstract

With the increasing focus on energy balance of buildings and simplifying of the building construction process, hollow clay bricks with cavities filled with thermal insulating material, are finding increasing popularity in the recent years. However, all of the commercially available products use either organic insulators or a combination of inorganic material with an organic binder for this purpose. In this work, foam glass was used as an insulating filler for hollow clay bricks as a more environmentally friendly substitute of common insulators with the aim to increase longevity, recyclability and fire resistance compared to the commercially available filled masonry blocks. Foam glass was prepared from waste packaging glass and limestone via powder sintering method. Influence of foaming agent content, water content, glass cullet particle size, foaming temperature and holding time on bulk density, pore size and morphology of foam glass samples was investigated. Possibilities of using foam glass to produce purely inorganic filled hollow clay bricks without any additional binders, by direct foaming of glass in the cavity of the brick, were investigated. Different approaches to manufacturing thermal insulating masonry blocks by foaming of glass inside fired hollow bricks were investigated. Lastly, we successfully prepared hollow bricks filled with foam glass by direct foaming of glass in the cavity of an unfired brick using firing regime similar to that of typical masonry ceramics. Prepared foam glass showed good adhesion to the ceramic body and low bulk density.
