In this work a new method of obtaining doloma-magnesia co-clinker, which involves fusing a mixture of dolomite decarbonate and caustic magnesia, has been presented. Fused dolomite clinker and fused doloma-magnesia co-clinker have been prepared from high purity raw materials. The properties of a fired material obtained from such co-clinker were compared with a product obtained from fused dolomite clinker without any addition of MgO and with a product enriched with magnesium oxide in the traditional way – by substituting the finest grain fractions with magnesia clinker. It has been proved that it is possible to obtain a fired doloma-magnesia material based on fused doloma-magnesia co-clinker characterized by high chemical purity as well as high resistance to corrosion, hydration and thermal shocks.
