Zusammenfassung:Chrome-free and anti-corrosive pigment mixture with less zinc, comprises at least one calcium hydrogen phosphate pigment (30-60 wt.%), at least one amorphous (15-45 wt.%), modified calcium silicon dioxide, at least one calcium boron silicate pigment (5-25 wt.%) and at least one zinc salt (1-15 wt.%) of an organic nitro compound with the zinc content of up to 10 wt.%. Independent claims are included for: (1) the preparation of anti-corrosive pigment mixture; and (2) use of the anti-corrosive pigment mixture for production of hardening materials.
