Claims19
A hydraulic binder comprising at least one latently hydraulic material and/or at least one pozzolanic material, wherein ternesite is included as an activator.
The use of ternesite as an additive for activating latently hydraulic and/or pozzolanic materials, wherein ternesite is mixed with the latently hydraulic and/or pozzolanic materials, and the two together, possibly with the addition of other components, are ground to form a cement, or the ground ternesite with the ground latently hydraulic and/or pozzolanic materials, possibly with the addition of other components, are mixed to form the binder.
A method for activating latently hydraulic and/or pozzolanic material in hydraulic binders, wherein ternesite is added.
