Abstract
A fast-curing mineral binder mixture includes a zirconium(IV)-based accelerator, a cement which includes at least one component selected from the compounds 3CaO*Al2O3, 12CaO*7Al2O3, CaO*Al2O3, CaO*2Al2O3, CaO*6Al2O3 and 4CaO*3Al2O3*SO3, and 15 to 80 wt % of a sulfate carrier, wherein the wt % is based on a weight of the fast-curing mineral binder mixture. The fast-curing mineral binder mixture can optionally include at least one alkaline component and/or at least one additive.

A fast-curing mineral binder mixture comprising:
- a zirconium(IV)-based accelerator;
- a cement comprising at least one component selected from the compounds 3CaO*Al2O3, 12CaO*7Al2O3, CaO*Al2O3, CaO*2Al2O3, CaO*6Al2O3 and 4CaO*3Al2O3*SO3;
- and
- 15 to 80 wt % of a sulfate carrier,
- wherein,
- the wt % is based on a weight of the fast-curing mineral binder mixture.
A method for producing a workable building material, the method comprising:
- mixing at least one of zirconium nitrate (Zr(NO3)4), zirconium(IV) sulfate (Zr(SO4)2), zirconium(IV) hydrogen phosphate (Zr(HPO4)2), zirconyl nitrate (ZrO(NO3)2), and zirconyl chloride (ZrOCl2) with water so as to provide a first mixture;
- and
- mixing the first mixture with a binder mixture comprising,
- a cement comprising at least one component selected from the compounds 3CaO*Al2O3, 12CaO*7Al2O3, CaO*Al2O3, CaO*2Al2O3, CaO*6Al2O3 and/or 4CaO*3Al2O3*SO3,
- 15 to 80 wt % of a sulfate carrier, and
- at least one of a regular filler and a lightweight filler,
- so a to provide the workable building material.
