| titleOfInvention | Process for producing blended cements with reduced carbon dioxide emissions |
| abstract | A process for producing blended cement, where the cement contains Portland Cement mixed thoroughly with a microfiller and possibly a water reducing agent to a dry cement mixture and fine supplementary cementitious materials selected from the materials blast furnace slag, fly ash, quartz, silica, amorphous silicon dioxide, limestone and recycled concrete. The invention is characterized in, that said supplementary materials in a first step are being subjected to a grinding in a dry state to a specific surface of at least 1000 cm2/g (Blaine), in that in a second step the supplementary grinded materials are being subjected to a grinding together with at least 20 % by weight of the total grinding mass of a highly reactive cement mixture in a dry state to achieve a specific surface of at least 3000 cm2/g (Blaine), which highly reactive cement mixture contains cement and at least one of the components a SiO2 containing microfiller and a polymer in the form of a powdery water-reducing agent which mixture have been previously been treated in a grinder with vibrating grinding media in which the cement particles are subjected to a large number of impact impulses giving the cement particles an increase in surface energy and chemical reactivity. |
