Brick raw materials quality in Serbia and the influence for the products quality and to the production technology - loess sediments

Kvalitet opekarskih sirovina u Srbiji varira u širokom opsegu u pogledu hemijskih, mineraloških, granulometrijskih i keramičko-tehnoloških karakteristika. Opekarske sirovine se mogu razvrstati u nekoliko osnovnih tipova i svaki tip ima odgovarajuće prednosti i ograničenja u primeni za proizvodnju određenih proizvoda i asortimana. U ovom radu daju se karakteristike lesnih sedimenata. Analiziran je uticaj kvaliteta lesnih sedimanata na kvalitet opekarskih proizvoda i na tehnološke parametre procesa proizvodnje.The quality of the brick raw materials in Serbia varies due theirs chemical, mineralogical, grain size characteristics, as well as technological properties. Brick raw materials may be classified in a few main types. For their application in the production of a certain product and assortment very main type has some advantages and limits. In this work we presents characteristics of loess sediments and their influence on production process and quality of the brick product
