A method for manufacturing a binder of a hydratable material includes providing a starting material from one or more raw materials convertible by tempering at 600 to 1200&#xb0; C. into the hydratable material, tempering the starting material to provide the hydratable material containing not more than 10% by weight monocalcium silicate and at least 15% by weight hydratable phases in the form of lime and dicalcium silicate, wherein the residence time and the tempering temperature are adapted to obtain the hydratable material by converting not more than 80% by weight of the starting material, and cooling the hydratable material to provide the binder comprising the hydratable material. The binder can be mixed with water and optionally one or more of aggregate, additives, admixtures to obtain a binder paste that is placed, hydrated and carbonated to produce a building product.

Method for simultaneous exhaust gas cleaning and manufacturing of supplementary cementitous material

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.
