Verfahren zur Herstellung eines Bindemittels für hydraulisch abbindende Fließestriche

Hydraulic binder for fluid flooring compsn. is based on a mixt. of Ca sulphate (I) and foundry sand (II) and also contains reactive aluminate (III), calculated as CA. The mixt. occupies an area in the triangular diagram bounded by 35-70 wt.% CaSO4 on the (I)-(II) axis and 0.5-5 wt.% (III) such that...

Zusammenfassung:	Hydraulic binder for fluid flooring compsn. is based on a mixt. of Ca sulphate (I) and foundry sand (II) and also contains reactive aluminate (III), calculated as CA. The mixt. occupies an area in the triangular diagram bounded by 35-70 wt.% CaSO4 on the (I)-(II) axis and 0.5-5 wt.% (III) such that a standard prism made from a mixt. of 3 pts. wt. quartz sand and 1 pt. wt. binder gives a shrinkage of less than 0.3, esp. less than 0.2 mm/m after conditioning for 28 days, comprising 21 days at 20 C/65% RH after keeping under humid conditions or in water.
