Abstract (en)

[origin: WO9514559A1] A method for producing a concrete, plaster, gypsum or corresponding mix by using water and binder hardening by the action of water and possibly mineral aggregate. The mix is mixed so rapidly in the mixing chamber of a mixing device that an essential early workability of short duration and a subsequent essential early stiffening are created. The mix is caused to move from the point of contact between water and binder to the discharge end of the mixing device and further directly into a casting mould or nozzle or onto a desired surface before the essential early workability of short duration occurring immediately after adding water is reduced and the essential early stiffening begins.
