    摘要： A method for manufacturing hydraulically hardening building materials, includes the steps of: providing concrete demolition waste with a maximum particle size of up to 150 mm as a starting material, mixing the starting material with water to form a feedstock slurry, introducing carbon dioxide or a precursor thereof into the feedstock slurry to form carbonated concrete fines in an amount from 1 to 100 wt.-% of the hardened binder contained in the starting material and to detach the concrete fines from the aggregate contained in the starting material to form a product slurry, and mixing the product slurry with a cement forming the building material, and use of the obtainable building material for manufacturing building structures as well as method for manufacturing a supplementary cementitious material slurry.

    摘要： 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.

    摘要： 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, stratlingite, 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.
