Description

Herstellung geformter Bauteile Das Patent 812 414 betrifft ein Verfahren zur Herstellung von Bauelementen unter Verwendung von natürlichem oder synthetischem Anhydrit. Dabei wird von der Erkenntnis Gebrauch gemacht, daß Anhydrit mit einer bestimmten Menge Wasser angemacht, durch geringen Druck sich plastisch verformen läßt, während angemachter Anhydrit ohne zusätzliche Druckbehandlung nur eine krümelige, evtl. sogar trockene Masse bildet. Eine zusätzliche Erhöhung des Wasseranteils über den optimalen Bedarf hinaus ist unter anderem wegen Verringerung der Druckfestigkeit des fertigen Produktes unangebracht.Manufacture of Shaped Components Patent 812,414 relates to a method for manufacturing components using natural or synthetic anhydrite. Use is made of the knowledge that anhydrite mixed with a certain amount of water can be plastically deformed by low pressure, while mixed anhydrite only forms a crumbly, possibly even dry mass without additional pressure treatment. An additional increase in the water content beyond the optimal requirement is inappropriate because of, among other things, a reduction in the compressive strength of the finished product.

Es wurde nun gefunden, daß eine derart angemachte krümelige, nicht plastische Masse aus Anhvdrit und wenig Wasser auch dann plastisch und damit verarbeitbar gemacht werden kann, wenn man sie einer intensiven Bewegung aussetzt, wie sie z. B. durch mechanische oder elektromagnetische Rüttelmaschinen, durch Schleudern oder durch Ultraschall erzeugt wird. Es werden zwar Rüttler oder Schleudern bereits bei der Herstellung von Bauteilen aus Beton verwandt, es war aber nicht zu erwarten, daß beispielsweise die Vibrationen einer Rüttelmaschine imstande waren, bei der zu verdichtenden :lasse die zur Plastifizierung erforderlichen Drucke zu ersetzen.It has now been found that a crumbly, so dressed, not plastic mass made of anhvdrite and a little water then also plastic and thus workable can be done if you subject them to intense movement, such as. B. by mechanical or electromagnetic vibrating machines, by centrifuging or generated by ultrasound. There are vibrators or slings already at related to the production of components from concrete, but it was not to be expected that, for example, the vibrations of a jogger were able to with the to be compressed: leave the prints necessary for plasticization to be replaced.

Zweckmäßig wird man gemäß der Erfindung so arbeiten, daß man die angemachte, krümelige Masse in Formen gibt und sie dann dem Rüttel- oder Schleuderprozeß aussetzt.Expediently, one will work according to the invention in such a way that the crumbly mass in forms and then the shaking or centrifuging process suspends.
