Abstract
The present invention relates to the production of ternesite clinkers containing 20 to 95% by weight C5S2$ and less than 15% by weight C4A3$, and to the use of ternesite as an additive to hydraulic and/or latent hydraulic and/or pozzolanic materials.
Claims21
A method for producing a ternesite clinker, comprising sintering a raw meal mixture, which contains at least sources for CaO, SiO2, and SO3, wherein a temperature during sintering is adjusted in the range of 900 to 1300° C. such that the ternesite clinker has a content of C5S2$ ranging from 20 to 95% by weight and a content of C4(AxF(1-x))3$, with x being 0.1 to 1, of less than 15% by weight, in each case relative to the total weight of the clinker.
