Description

Verfahren zur Herstellung von porösen Baustoffen Zusatz zum Patent 42, 777 Das Hauptpatent hat ein Verfahren zur Herstellung von porösen Baustoffen aus mit Wasser oder anderen Flüssigkeit-en zu mischenden Mitieralstoffen zum Gegenstand, bei welchem zum künstüchen Porösmachen des Materials der Mischungsflüssigkeit auf mechanischem Wege hergestellter Schaum zugesetzt wird.Process for the production of porous building materials Addition to patent 42, 777 The main patent relates to a process for the production of porous building materials from Mitieralstoffen to be mixed with water or other liquids, in which to artificially porosity of the material of the mixing liquid foam produced by mechanical means is added.

Die Erfindung bezIeht sich auf eine weitere Ausgestaltung dieses Verfahrens und besteht darin, daß die Schaummörtehnischung in hochgespanntem. Dampf gehärtet wird.The invention relates to a further embodiment of this method and consists in that the foam mortar mixture in high tension. Steam hardened will.

Als allgemein bekannt vorausgesetzt wird hierbei die Anwendung hochgespannten Dampfes zum Härten von Gegenständen, z. B. Bausteinen, die mit hydraulischen Bindemitteln eingebunden sihd. Die Dampfeinwirkung erfolgt hier also erst dann, wenn ffie Werkstoffe durch Pressen oder Stampfen einen gewissen Zusammenhang erhalten haben und hat nur eine Beschle=i*lgung bei der überfüh.-rung der Gegenstände in den Fertigzustand zur Folge.The application is assumed to be generally known Steam for hardening objects, e.g. B. Building blocks made with hydraulic binders integrated sihd. The steam only takes effect here when the materials by pressing or pounding have and only has a certain connection an acceleration in the transfer of the objects to the finished state result.

Durch die Anwendung der Härtung einer Schaununörtelmischung In hochgespanntein Dampf bei der Herstellung poröser Baustoffe nach dem Hauptpatent werden besondere Vorteile in verschiedener Hinsicht erzielt. Die Schaunimörtehnischung läßt sich ihrer Natur nach nicht stampfen und muß daher meist aus fett-en Mörteln hergestellt wexden. Durch die Härtung inhochgespanntemDampf wird zunächst das sogenannte Sacken des Materials wirksam unterbunden. Dann abar löst die Dampfhärtung dIe besondere Wirkung aus, daß der Trocknungsschwund nur etwa 1/3 bis 1/4 so groß Ist wie bei nicht dampfgehärteten Schaummörtelmischungen. Gerade das Schwinden ist für diese Stoffe von besonderer Bedeutung, da wegen der fetten Mischungen und der großen Wassermengen vor der Fertigstellung eine starke Austrocknung stattfinden muß. Durch die Herabsetzung dieses Schwurüles wird das Enderzeugnis volumenbeständiger und, Rißbildungen beim Trocknen werden v-ermlqden.By using the hardening of a Schaununortel mixture in high tension steam in the production of porous building materials according to the main patent, special advantages are achieved in various respects. The Schauni mortar mix cannot be tamped by its nature and must therefore mostly be made from grease-en mortars. By curing in high-tension steam, the so-called sagging of the material is first effectively prevented. Then the steam curing triggers the special effect that the drying shrinkage is only about 1/3 to 1/4 as large as with non-steam-hardened foam mortar mixtures. It is precisely the shrinkage that is of particular importance for these substances, as the fatty mixtures and the large amounts of water mean that they must dry out to a great extent before they are finished. By reducing this oath, the end product is more stable in volume and cracks are formed during drying.

Es hat sich als vorteilhaft erwiesen, dem Mörtelbrei solche Stoffe biea'zumischen, die einen Teil der verhältnismäßig großen Wasserinenge# die bei, der Herstellung von porösen Stoffen mit Schaum notwendig ist,binden können.It has proven advantageous to add such substances to the mortar slurry biea 'to mix, which is part of the relatively large amount of water the production of porous materials with foam is necessary to be able to bind.

Als Beispiel für die Herstellung ist ein aus Kalk und Sand bestehender Mörtel anzusehen, dem als Zusatzstoffe Zement, hydraulisc'he Zuschlagstoffe, Quarzniebil o.dgl. oder Mischungen von solchen Sto-ffen beigegeben werden können.As an example of the production, a mortar consisting of lime and sand is to be considered, to which cement, hydraulic aggregates, quartzniebil or the like as additives. or mixtures of such substances can be added.

Gut ist z. B. folgende Aüschung (nach Gewicht): 6,3% Kalkmehl (0a0), 63,50/0 Sand, 2,5% Schm6lzzement, 50/0 Quarzmehl, 22,70/0 Wasser.Is good z. B. the following ash (by weight): 6.3% lime flour (0a0), 63.50 / 0 sand, 2.5% molten cement, 50/0 quartz flour, 22.70 / 0 water.

Als geeigneter schaumbildender Stoff ist Harzseife trät Zusatz von Gelatine festgestellt worden.Resin soap is recommended as a suitable foam-forming substance Gelatin has been found.

Die Härtungsdauer beträgt etwa 8 bis io Stunden bei 8 bis io Atm, Druck, nachdem ein Alter von 12 bis 36 Stunden erreicht ist.The curing time is about 8 to 10 hours at 8 to 10 atm, pressure after an age of 12 to 36 hours is reached.
