THE REGULATION OF PHYSICAL AND MECHANICAL PARAMETERS OF CERAMIC BRICKS DEPENDING ON THE DRYING REGIME

In the scientific studies the in influence of burning regime or composition of format ion mix on the final properties of the ceramic bricks is analysed most often. However, drying regime is also of paramount importance in the process of the high quality ceramic production. The formed ceramic samples were dried according to 8 different drying regimes while burning regime was not varied during the investigation. The dried samples were burnt for 24 hours keeping the maximum temperature 1050 degrees C for 3 hours. Later oil these parameters were determined experimentally: density, general shrinkage, compressive strength and rate Of ultrasound spread. As the statistical and regression analyses of data were performed, the empirical equations. showing how the selected stages of drying regime influence the physical and mechanical parameters of ceramics, and vice versa.. how the selection of the dimensions of the stages of drying regime depends oil the desired values of the ceramics properties, were derived.
