The invention relates to a method for producing a curable composition, and especially to a dolomite binder composition, which can be mixed with fillers and additives to produce a set of cured compositions, as well as a composition and a manufacturing product made using the specified composition. According to the present invention, there is claimed a method for preparing a curable composition of a binder containing a mixture of calcium carbonate and caustic magnesium oxide, which consists in heating dolomite of natural origin at a temperature in the range from 500 to 800 ° C to ensure preferred decarbonation of magnesium carbonate by releasing carbon dioxide while 2 to 50% of carbon dioxide remains in magnesium carbonate without substantially decarbonating calcium carbonate, resulting in esi magnesium oxide, magnesium carbonate and calcium carbonate (MgO, CaCO MgCOi). |
