METHOD FOR PRODUCING CEMENT COMPRISING A SUPPLEMENTARY CEMENTITIOUS MATERIAL, AND CEMENT OBTAINABLE THEREBY
The invention is concerned with a method for producing a cement comprising milled cement clinker and a supplementary cementitious material, wherein the method comprises the steps of: producing the milled cement clinker by a clinkerization process, comprising the steps of calcining and subsequently milling a limestone-based raw material; producing the supplementary cementitious material by calcining a raw material of the supplementary cementitious material at a temperature of less than 980°C and subsequently milling the calcined raw material of the supplementary cementitious material, wherein the raw material of the supplementary cementitious material has an average particle size of 1 to 300 mm, wherein at least 5 wt% of the particles have a particle size of above 4.75 mm; and blending the milled cement clinker and the supplementary cementitious material. Further, the invention is concerned with a Method for producing a cement comprising milled cement clinker and a supplementary cementitious material, wherein the method comprises the steps of: producing the milled cement clinker by a clinkerization process, comprising the steps of calcining and subsequently milling a limestone-based raw material; producing the supplementary cementitious material by calcining a raw material of the supplementary cementitious material at a temperature of less than 980°C and subsequently milling the calcined raw material of the supplementary cementitious material, wherein the raw material of the supplementary cementitious material has an average particle size of 1 to 300 mm; and blending the milled cement clinker and the supplementary cementitious material; wherein the method is a continuous process comprising the step of calcining the raw material of the supplementary cementitious material in a kiln with a separate heating unit and/or combustion unit. The invention is also concerns a cement comprising milled cement clinker and a supplementary cementitious material, wherein the supplementary cementitious material comprises an amorphous constituent of more than 30 wt% as measured by XRD, wherein the supplementary cementitious material comprises less than 70 wt% of inert components selected from the group comprising mullite, spinel, feldspar, diopside, mica, or combinations thereof, and wherein the color of the cement in the range of 130-160, 130-160, 120-160, wherein the measurement of the cement color is conducted by a RGB2 colorimeter, wherein the colors are referenced to a RGB scale of 0 to 255.
