Frost Resistant Ceramics Produced from Local Raw Materials and Wastes

The aim of this work was to analyse the possibilities to produce frost resistant ceramic body from local raw materials and wastes. Additional task is to investigate the influence of two waste materials (sawdust and milled windows glass) utilised together in the formation mass and burning temperature on the properties of ceramic masonry products. After analysis of research results, it was found that, it is possible to produce high frost resistivity ceramic with forecasted frost resistance larger than 1300 cycles and with effective porosity, determined after three days, lower than 6%. Moreover, by using local raw materials and additives, the porous frost resistant ceramics was obtained. The total open porosity of this ceramics reaches 35%, and forecasted frost resistance by beginning of disintegration is higher than 100 cycles.
