Description
Verfahren zur Herstellung von Bauelementen. Bei. der Extraktion von Kastanien-, Eiehen- oder Quebrachoholz zwecks Gewin- nung von Gerbstoffen werden Abfälle erhal ten, für die man bisher keine bessere Ver wendung als die Verfeuerung gefunden hat.
Es wurde nun .gefunden, @dass man, aus derartigen Abfallstoffen vorteilhaft Bau elemente, wie Blöcke, .Steine, Platten und ,dergleichen herstellen kann, die sieb. durch gutes Isolationsveamögen ,gegenüber Sckall und Kälte, beziehungsweise Wärme, sowie durch Schwund- und Wasserbeständigkeit auszeichnen.
Das erfindungsgemässe Verfahren zur Herstellung von Bauelementen ist .dadurch gekennzeichnet, dass man bei der Gerbstoff extraktion anfallende Holzrückstände mit Zement und einem feinkörnigen Gestein innig vermengt, das Gemisch mit Wasser be handelt, zu Bauelementen, verformt und er härten, lässt.
Man kann zur Herstellung von Bar elementen beispielsweise folgendermassen ver fahren: Die obergenannten Holzabfälle wer- den mit Zement und Marmormehl etwa im Verhältnis 5 : 1 : 1 ,gut gemischt, mit Wasser angefeuchtet und dann in üblicher Weise .geformt und gepresst.
Die so erhaltenen. Presslinge werden so dann auf einem laufenden Band -durch ein mit gesättigtem Dampf gespeistes Rohr ge- führt, in dem sie weiter erhärten.
Man kann den Holzrückständen auch ge mahlene Maisstengel und/oder Maiskolben zusetzen. A<B>n</B> iStelle von Marmormehl kann auch ein anderes Gesteinsmehl oder Sand ver- wendet werden.
Ferner kann man, um eine möglichst tiefgehende "Versteinerung" jder Holzrückstände zu bewirken, diese vor dem Zusatz von Zement mit Wasserglas und dann mit Kalkmilch behandeln.
Process for the production of components. At. the extraction of chestnut, eehmen or quebracho wood for the purpose of extracting tannins produces waste for which no better use than incineration has been found so far.
It has now been found, @that, from such waste materials advantageous construction elements, such as blocks, .Stones, plates and the like can produce the screen. characterized by good insulation properties, against sckall and cold or heat, as well as shrinkage and water resistance.
The inventive method for the production of building elements is characterized in that wood residues resulting from the tannin extraction are intimately mixed with cement and a fine-grained rock, the mixture is treated with water, formed into building elements, and it is allowed to harden.
For example, the following procedure can be used to produce bar elements: The above-mentioned wood waste is mixed well with cement and marble powder in a ratio of about 5: 1: 1, moistened with water and then shaped and pressed in the usual way.
The thus obtained. Pressings are then guided on a moving belt through a pipe fed with saturated steam, in which they harden further.
You can also add ground corn stalks and / or corn cobs to the wood residues. A <B> n </B> iInstead of marble powder, another rock powder or sand can be used.
Furthermore, in order to "petrify" any wood residues as deeply as possible, treat them with water glass and then with milk of lime before adding cement.
