摘要： Activators for supplementary cementitious material, comprising reactive belite, obtainable by hydrothermal treatment of a starting material, which contains sources for CaO and SiO2 in an autoclave at a temperature of 100 to 300° C. and tempering the obtained intermediate product at 350 to 495° C., hydraulic binders based on the supplementary cementitious material above, and by a method for activating the supplementary cementitious material by adding reactive belite obtainable by hydrothermal treatment of a starting material which contains sources for CaO and SiO2 in an autoclave at a temperature of 100 to 300° C. and tempering the obtained intermediate product at 350 to 495° C. and the use of the reactive belite containing material as activator.

摘要： The invention relates to a method for producing cements by hydrothermally treating a starting material containing sources of CaO and SiO2 in an autoclave at a temperature of 100 to 300° C., and tempering the obtained intermediate product at 350 to 700° C., wherein water formed during tempering is dissipated by grinding the intermediate product and/or tempering taking place under a continuous gas stream. The invention also relates to cements obtained in this manner, hydraulic binders therefrom, and building materials which contain said binders.
