Abstract: Composite cement with improved reactivity and improved fresh properties comprising a hydraulic cement or a caustic activator, a hyaloclastite as pozzolan containing 45-62 wt.-% SiO2, 10-20 wt. % Al2O3, 6-15 wt.-% Fe2O3, 7-15 wt.-% CaO, 7-15 wt.-% MgO, 1.5-4 wt. % (K2O+Na2O), and having 0-5 wt.-% loss on ignition at 950° C. and ≥50 wt.-% X-ray amorphous phase, and a carbonate filler with an at least bimodal particle size distribution adapted to provide a slope n in a Rosin-Rammler-Sperling-Bennett distribution curve of ≤1.15 in a particle size distribution of the composite cement; a method for manufacturing it, as well as use of a composition comprising the hyaloclastite as pozzolan and the carbonate filler as mineral addition for composite cements comprising a hydraulic cement or a caustic activator.

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.
