Claim 13:
14. A method of using 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) as the zirconium(IV)-based accelerator for the fast-curing mineral binder mixture as recited in claim 1, the method comprising:
providing 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) as the zirconium(IV)-based accelerator; and
adding the 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) as the zirconium(IV)-based accelerator to 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 to 15 to 80 wt % of a sulfate carrier so as to provide the fast-curing mineral binder mixture, wherein, the wt % is based on a weight of the fast-curing mineral binder mixture,
wherein,
the 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) as the zirconium(IV)-based accelerator is used so as to accelerate a curing of the fast-curing mineral binder mixture.
