Abstract: Secondary raw materials include various types of recycled glass. Production processes connected with raw glass, or more precisely glass products, are focused mainly on their visual features (colour, transparency, etc.) which are significant or even crucial criteria for their competitive advantage in the market. With respect to this fact recycled raw glass cannot always be fully utilized in glass production, i.e. it cannot fully replace glass stone which is the basic raw material for glass production, but it can be used partially (this fact is closely connected with the high purity requirements for fragments and it depends on product types).
Probably the best known types of raw glass in connection with recycling are clear and coloured bottles and containers and ordinary flat glass obtained mainly from demolished buildings or car wrecks. Some types of raw glass are not suitable for glassworks at all.
Electrical products with expired lifespan, i.e. fluorescent lamps, spotlights, lamps, car headlamps, etc. are worth mentioning. A significant volume of glass waste is also obtained from disassembled useless TV screens and computer monitors. In the area of utilization of secondary raw materials obtained from glass recycling several researches have been carried out in many ways (cement composites, macromolecule-based plastering mixtures, glass ceramics, etc.) but no fully satisfying results which would solve these issues complexly have been achieved.
Production of sintered materials from glass offers a wide range of ways how to utilize recycled glass which has not been utilized at all yet and, therefore, harms the environment due to its disposal. The paper is focused on sintered materials from recycled glass as a material and their utilization in the building industry. Their physical and chemical parameters (strength, chemical resistance, thermal expansion, heavy metals and toxic elements leach etc.) are investigated.
