dc.description.abstractDifferent forms of wastes like sewage sludges, bagasse, sawdust, papermaking sludge, olive oil waste, tobacco residues, urban waste water sludge, brewing industry sludge, biomasses, etc. are used as pore-forming agents in the manufacture of ceramic bricks. These wastes modify the microstructure of clay improving its thermal conductivity. Diatomite is used as a filtration medium the brewing industry. A sludge containing diatomite and organic material retained during the clarification process is used as a by-product. The effect of the dried diatomite containing a brewing industry waste by-product in quantities of 0 mass %, 3 mass %, 5 mass %, 8 mass %, 11 mass % and 14 mass % on the water absorption, apparent density, apparent porosity, compressive strength and thermal conductivity of porous clay samples fired et 900oC is investigated. There is no change of the fired material properties in case of a minimum (3 mass %) content of a brewery waste. The fired clay material properties vary proportionally to further waste amount increase. It is found that the water absorption and the apparent porosity increase, while the apparent density, the thermal conductivity and the compressive strength decrease with increase of the brewery waste content.
