Microstructure modelling of ceramic tile systems and frost resistance characteristics
Frost resistance of ceramic tiles is one of the most important characteristics of these products, which is directly connected with the microstructure features of the final product: pore size distribution and pore permeability. As the microstructure of the final product (biscuit) is closely connected with the raw material characteristics and processing parameters, the study is focused on the quantification of these parameters with the aim of revealing the behaviour of the ceramic matrix during freezing action. Two groups of tiles were the subject of the investigation: one which failed in strong climate conditions-real systems, and a second, which involved model systems based on kaolinite I illite-carbonate compositions. The model samples were shaped by dry pressing and fired at 960 deg C and 1050 deg C in laboratory conditions. A promising tool in the procedure of modelling frost resistant ceramic tiles has been established, based on the correlation of pore size distribution of the fired tiles and model systems, freezing dilatation values and DSC results (-40 up to +40 deg C).
