Abstract

A study was carried out on the incorporation in a real enirontment of fabricated innovative building elements. The investigated elements include products such as rectangular plates, “П” and semi “O” shaped elements, all made of composite material consisting of spherical foam glass granules bonded with a suitable multi-component cement mixture and manufactured by a specially developed technology. The elements have a specific shape, dimensions and particular physical and mechanical characteristics, thermal and acoustic insulation properties and fire-resistant qualities. The aim of the study is to incorporate them into given construction objects, mainly buildings, and to determine the efficiency and efficacy of the process of incorporating the building elements into a real building structure
