Claims (13)

1. Ultrahurtigt størknende cementsammensætning, omfattende mindst et amorft calciumaluminat, omfattende i vægt i forhold til totalvægten af det amorfe calciumaluminat: (a) fra 35 til 55 % calciumoxid CaO (C), (b) fra 19 til 55 % aluminiumoxid AI2O3 (A), hvorved det molare forhold C/A er større end eller lig med 1,5, (c) fra 0 til 10 % siliciumdioxid S1O2, kendetegnet ved, at det amorfe calciumaluminat (d) omfatter fra 5 til 16 % jernoxid Fe2C>3.
2. Cementsammensætning ifølge krav 1, hvorved det amorfe calciumaluminat i vægt, i forhold til totalvægt af det amorfe calciumaluminat, omfatter fra 5 til 10 %, fortrinsvis fra 5 til 8 % jernoxid (d).
3. Cementsammensætning ifølge et af de foregående krav, hvorved det amorfe calciumaluminat i vægt, i forhold til totalvægt af det amorfe calciumaluminat, omfatter fra 42 til 52 %, fortrinsvis fra 47 til 51 % calciumoxid (a).
4. Cementsammensætning ifølge et af de foregående krav, hvorved det amorfe calciumaluminat i vægt, i forhold til totalvægt af det amorfe calciumaluminat, omfatter fra 25 til 48 %, fortrinsvis fra 34 til 42 % aluminiumoxid (b).
5. Cementsammensætning ifølge et af de foregående krav, ydermere omfattende i vægt, i forhold til totalvægt af det amorfe calciumaluminat, fra 1 til 8 %, navnlig fra 3 til 6 % siliciumdioxid S1O2 (c).
6. Cementsammensætning ifølge et af de foregående krav, hvorved det amorfe calciumaluminat har en opløsningshastighed i vand, som er større end eller lig med 15.10'6 mol.s"1.nr2.
