摘要： The present invention falls within the field of building materials, particularly in the production of cement. It is specifically referred to the production of a cement which is obtained from a low-carbon clinker. The present invention provides a development in cement production with respect to the known cements, thus obtaining a cement with low greenhouse gases emissions, reducing the specific heat consumption and increasing chemical resistance, while maintaining all its functional properties.

摘要： Method for producing a low-carbon clinker with low energy consumption comprising the following stages: pre-calcination of the limestone present in the raw material, along the pre-calciner and in the cyclone tower; start of the clinkering process with the raw material inlet after pre-calcination, at a temperature higher than 1400° C. and with a C3S content above 60%; cooling the material, and finally introduction of 5 to 30% of silico-aluminous materials relative to the mass of material which is here processed in the cooling stage, at the cooler head.
