Description

Verfahren zur Herstellung von Formsteinen, vornehmlich Dachplatten Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Dachplatten . sowie Formsteinen, gegebenenfalls solchen mit niederem Raumgewicht.Process for the production of shaped stones, mainly roof panels The present invention relates to a method for producing roof panels . as well as shaped stones, possibly those with a low density.

Das erfindungsgemäße Verfahren besteht darin, da.ß man amorphe Kreide als Ausgangsmaterial mit anorganischen Bindemitteln vermischt und nach der Verformung dampfhärtet. Insbesondere wird das Verfahren in folgender Weise ausgeführt: Es wird natürliche amorphe Kreide, die unter Umständen gemahlen werden muß, verwendet, mit Wasser angeteigt und dem so erhaltenen Brei eine aus Kieselsäure, z. B. feinem Quarz, undeinem basischen Bestandteil, z. B. hydratisiertem Kalk, bestehende Mischung als Bindemittel beigemengt, wobei .der Kalk teilweise in gebrannter Form zwecks kurzer Abbindezeit vorliegen kann. -Die so erhaltene Masse wird entweder a) durch Gießen, Rütteln oder Pressen zu festen Bausteinen bzw. Dachplatten oder b) .durch Zugabe von,dosierter Menge üblicher Schaummittel zu porösen Bausteinen mit verschiedenem Raumgewicht verformt.The inventive method consists in that amorphous chalk mixed as a starting material with inorganic binders and after deformation steam cures. In particular, the method is carried out in the following way: It is natural amorphous chalk, which may need to be ground, used with Water made into a paste and the resulting pulp a silica, z. B. fine quartz, and a basic component, e.g. B. hydrated lime, existing mixture as Binder added, with .the lime partly in burnt form for the purpose of short There may be setting time. -The mass obtained in this way is either a) poured, Vibrating or pressing into solid building blocks or roof panels or b). By adding from, dosed amount of conventional foam concentrate to porous building blocks with different Deformed volume weight.

Die nach den obigen Methoden hergestellten geformten Körper werden anschließend bei etwa 7 at wasserdampfgehärtet.The molded bodies produced by the above methods will be then steam hardened at approx. 7 at.

Die nach dieser Arbeitsweise hergestellten festen Formsteine bzw. Dachplatten zeichnen seich ,dadurch aus, idaß sie den normalen geforderten Normen völlig entsprechen, insbesondere diese in ihrer Druckfestigkeit überschreiten und auch bezüglich der-Frost- und Wasserbeständigkeit.den gestelltem. Anforderungen genügen. .The solid shaped bricks or bricks manufactured according to this procedure Roof panels are characterized by the fact that they meet the normal required standards completely correspond, in particular exceed them in their compressive strength and also regarding the frost and water resistance. Requirements met. .

Beispiel 75 Teile Kreide, 15 Teile Hydratisierter Kalk, 5 Teile gebrannter Kalk, 5 -Teile Quarz, gemahlen, -werden. gemischt. Diese Mischung wird bis zur Er-, zielung einer formbaren Masse mit Wasser versetzt, geformt und bei etwa 7 at wasserdampfgehärtet.' Ein weiterer Vorteil besteht darin, daß -die festen Formsteine bzw. Dachplatten im Vergleich zu Ziegelsteinen bzw. Tonda chplatten ein erheblich leichteres Gewicht aufweisen, wobei das Raumgewicht der festen Formsteine. zwischen 1,2 und 1,6 und das der porösen (geschäumten) Körper zwischen o,8 und i beträgt.Example 75 parts chalk, 15 parts hydrated lime, 5 parts quicklime Lime, 5 parts quartz, can be ground. mixed. This mixture is Aiming a malleable mass mixed with water, shaped and hardened at about 7 atm. ' Another advantage is that the solid shaped stones or roof panels Compared to bricks or clay plates, it is considerably lighter in weight have, the density of the solid shaped bricks. between 1.2 and 1.6 and that of the porous (foamed) body is between 0.8 and i.
