Abstract

The present invention relates to a composite cement obtainable by grinding Portland cement clinker and latent hydraulic material together, preferably in the presence of at least one amine grinding aid, to provide a ground mixture and combining the ground mixture with a mineral filler. It further relates to a method of manufacturing the composite cement comprising the steps of grinding a latent hydraulic material and a portland cement clinker together, preferably in the presence of at least one amine, to provide a ground mixture and combining the ground mixture with one or more mineral fillers as well as to binders and to using the cement or binders as building material.
