  • Patent number: 11111180
    Abstract: A method of manufacturing building elements has the steps: providing a binder comprising at least 8% by weight ternesite, at least 15% by weight dicalcium silicate and at least 5% by weight ye'elimite, each with respect to the total binder, as hydraulically reactive phases; mixing the binder with water to form a paste; casting the paste into a desired shape for the building element; reacting the paste hydraulically to form calcium-silicate-hydrates, calcium-aluminium-silicate-hydrates, portlandite, brucite, strätlingite, hydrotalcite-like phases and ettringite/AFm and capillary pores, and carbonation hardening to provide the building element and to building elements obtainable by the method.

  • Patent number: 11001527
    Abstract: 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.

  • Publication number: 20200392043
    Abstract: 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° 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.

  • Patent number: 10766818
    Abstract: This invention relates to a method for producing a supplementary cementitious material comprising the steps: providing a starting material containing dolomite and aluminium silicate, converting the starting material to the supplementary cementitious material by burning under reducing conditions in the temperature range of >700 to 1100° C. or by burning in the temperature range of 625 to 950° C. in the presence of a mineraliser, and cooling the supplementary cementitious material. The invention further relates to a binder comprising cement and to the ground supplementary cementitious material.
