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.
