Abstract In order to elaborate low temperature dolomite ceramics, potentially suitable for the production of building materials, local low carbonate clay and dolomite siftings were used as a raw materials. Relationship between mechanical properties, mineral composition and firing temperature kept in the range of 600-800o C were established. According to the obtained data it was detected that the optimal burning temperature, giving the highest crushing strength (40 MPa) was around 700-750o C, optimal proportion of dolomite and clay expressed as ratio between CaO and Al2O3 - 2.5 wt%. Gradual formation of C3A occurs during firing, yielding C4AHx , i.e. mainly C4AH13 after hydratation of obtained composite material. The work was carried out in the frame of project „Innovative low temperature composite materials from local mineral deposits” (No 2010/024/2DP/2.1.1.1.0/10/APIA/VIAA/152) financed by the European Regional Development Foundation (Activity 2.1.1.1.).
