  • Patent number: 10626052
    Abstract: The invention provides novel, microstructured clinker and cement materials that are characterized by superior grindability and reactivity. The disclosed clinker and cement materials are based on carbonatable calcium silicate and can be made from widely available, low cost raw materials via a process suitable for large-scale production. The method of the invention is flexible in equipment and processing requirements and is readily adaptable to manufacturing facilities of conventional Portland cement.

  • Patent number: 8852339
    Abstract: The present invention relates to a process for the production of a clinker with a high content of belite, said process comprising the following steps: (i) introducing a raw meal into a calcination chamber of a cement plant kiln; (ii) calcining the raw meal at a temperature of from 1150° C. to 1375° C.; (iii) measuring the weight per liter of the product of step (ii) and eliminating the product having a weight per liter strictly less than 650 g/liter; (iv) measuring the quantity of SO3 in the product of step (ii) and eliminating the product having a ratio of quantity of SO3 of the decarbonated raw meal/quantity of SO3 in the product of step (ii) less than or equal to 0.75 and greater than or equal to 1.2; (v) measuring the quantity of free lime (CaOl) in the product of step (ii) and eliminating the product having a quantity of free lime strictly greater than 1.5%, percentage by mass of free lime in the product of step (ii).
