Abstract
The invention relates to a method for producing a belite-based binder consisting in reacting a starting material consisting of calcium oxide CaO and silicon oxide SiO<SUB>2</SUB> at the Ca: Si molar ration of approximately 2:1 with an a-dicalcium silicate hydrate crystallisation seeds, in hydrothermally treating the thus modified starting material at a temperature ranging from 100 to 300 °C, wherein said material is substentially converted into an intermediate a-dicalcium silicate hydrate material, in drying said intermediate material at a temperature of 500-1000 °C and in subsequently cooling it in such a way that a desired belite-based binder is separated. The use of the crystallisation seeds makes it possible to reduce the reaction time and to increase the conversion rate. The starting material can be embodied in the form of waste residues. The inventive method is carried out at low temperatures and with a low mechanical energy consumption. When it is possible to use an already decarbonated starting material, said method reduces a CO<SUB>2 </SUB>emission in a construction material area.
