METHOD FOR PRODUCING A MAGNESIUM SILICATE BELITE CALCIUM ALUMINATE CEMENT
The present invention relates to a method for producing a binder comprising the following steps: a) providing a starting material, from raw materials, that has a molar (Ca+Mg)/(Si+Al+Fe) ratio from 1 to 3.5, a molar ratio Ca/Mg from 0.1 to 100, and a molar Al/Si ratio from 100 to 0.1, wherein constituents that are inert during the hydrothermal treatment in an autoclave are not taken into account for determination of the ratios, b) mixing the raw materials, c) hydrothermal treating of the starting material mixture produced in step b) in an autoclave at a temperature from 100 to 300 °C and a residence time from 0.1 to 24 h, wherein the water/solids ratio is 0.1 to 100, d) tempering the intermediate product obtained in step c) at 350 to 600 °C, wherein the heating rate is 10-6000 °C/min and the residence time is 0.01-600 min. The present invention additionally relates to a binder obtainable in this way, and to the use thereof.
