Method for producing magnesium silicate-belite-calcium aluminate cement
The present invention relates to a method for producing a binder, comprising the steps of: a) providing a starting material with a molar Ca+Mg/(Si+Al+Fe) ratio of 1.0 to 3.5, a molar Ca/Mg ratio of 0.1 to 100 and a molar Al/Si ratio of 100 to 0.1 - the determination thereof disregarding constituents behaving inertly under hydrothermal autoclave treatment - from raw materials, b) mixing the raw materials, c) hydrothermally treating the step-b) mixture of starting materials in an autoclave at a temperature of 100 to 300 DEG C for a dwell time of 0.1 to 24 h at a water/solids ratio of 0.1 to 100, d) heating the step-c) intermediate at 350 to 600 DEG C with a heating rate of 10-6000 DEG C/min and a dwell time of 0.01-600 min. The present invention relates also to a binder obtainable accordingly, and to its use. The invention also relates to the obtained binder and use thereof.
