Originální abstrakt

Today's technology of ceramic tiles production uses only natural raw materials (kaolin, feldspar, clay, quartz, limestone etc.). In the Czech Republic, the annual production of wall and floor tiles amounts to more than 32 million square meters in the year 2004; mining raw materials for such a volume results in significant damages to the landscape. The aim of this paper is to investigate the possibility of waste materials using for the production of dry pressed ceramic tiles. By using of power plant fly ashes and firing of the raw material mixtures at 1100 - 1200 Celsius degrees, it was possible to prepare a ceramic body with properties which correspond to those of dry pressed ceramic tiles manufactured from pure natural raw materials (mostly alumino-silicates) according to EN 14411 standard. This paper describes the properties of the fired fly ash bodies according to ISO 10 545 standards (e.g. water absorption, bending strength, bulk density) and examines the firing fly ash body microstructure (for example pore structure by high pressure mercury porosimetry to anticipate of the frost resistance).
