Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines natürlichen Grund-Baustoffs aus Lehmböden.The invention relates to a method for producing a natural basic building material from clay soils.
Lehmböden sind ein Gemisch aus Ton, Schluff und Sand und sind praktisch überall auf der festen Erdkruste vorhanden und gewinnbar. Die Lehmbauweise ist daher älter als der Back steinbau und der Betonbau. Die älteste bekannte Lehmarchitektur ist durch den Städtebau in Jericho und durch den Turmbau von Babel belegt, wogegen in Afrika noch heute Beispiele für Lehm als Architektur vorzufinden sind.Clay soils are a mixture of clay, silt and sand and are practically everywhere on the solid earth's crust and recoverable. The loam construction is therefore older than the baking stone construction and concrete construction. The oldest known clay architecture is due to the urban development in Jericho and the tower construction documented by Babel, whereas examples of Clay can be found as architecture.
Der Lehm besitzt ein hervorragendes Wasserspeichervermögen und eine Wasserdurchlässigkeit, die mit einer guten Durchlüftung einhergeht. Dies ist auf seinen Sandanteil zurückzuführen, der ausreichend große freie Porenzwischenräume für die Wasser- und Luftaufnahme freiläßt. Der Tonanteil des Lehms ist für seine besonders gute Bildsamkeit verantwortlich, die die Fähigkeit des Lehms zu starker Verformung ohne Rißbildung bezeichnet.The clay has an excellent water storage capacity and a water permeability with good ventilation goes along. This is due to its sand content, the sufficiently large free pore spaces for the water and Aerial view leaves blank. The clay portion of the clay is for his particularly good plasticity responsible which is the ability of the clay is called excessive deformation without cracking.
Der Hauptnachteil des Lehms als Baustoff besteht darin, daß er wegen seiner unterschiedlichen Mengenanteile der drei Haupt komponenten unterschiedliche Ausgangseigenschaften hat, die zu unterschiedlichen Endeigenschaften der Lehmbaustoffe führen. Man kann also keine bestimmten Festigkeiten und Eigenschaften eines Lehmbaustoffs garantieren bzw. nach festen Mischregeln herstellen. Andererseits lädt sich Lehm auch zu unterschiedlichen Lehmbaustoffen verarbeiten, nämlich zu Stampflehm, zu Lehmziegelbau und als Ausfüllmaterial für den Lehmfachwerkbau, als Mörtel und als Putz. Man kann für diese unterschiedlichen Anwendungsformen von Lehmbaustoffen keine allgemeingültigen festen Mischrezepte festlegen und anwenden, weil die örtlichen Lehmböden in ihrer Zusammensetzung stark schwanken.The main disadvantage of clay as a building material is that it because of its different proportions of the three main components has different initial properties that too different end properties of earth building materials. So you can not have certain strengths and properties of an earth building material or according to fixed mixing rules produce. On the other hand, clay also invites to different ones Process earth building materials, namely rammed earth Adobe construction and as filler material for adobe framework construction, as mortar and plaster. One can go for these different ones Forms of use of earth building materials are not generally applicable determine and apply fixed mixing recipes because the local ones Clay soils vary widely in their composition.
Die Erfindung geht von der Erkenntnis aus, daß die Lehm böden, die für eine Verwendung als natürliche Grund-Baustoffe bestimmt sind, in ihren Eigenschaften durch eine bestimmte Vorbehandlung vereinheitlicht und standardisiert werden müssen, damit unter Anwendung bestimmter gleichbleibender Mischrezepte immer gleiche und garantierte Festigkeiten und Eigenschaften in den Endprodukten entstehen, gleichgültig ob es sich um Stampflehm, Lehmformsteine, Mörtel oder Putz handelt.The invention is based on the knowledge that the clay floors that are intended for use as natural basic building materials are determined in their properties by a certain Pretreatment must be standardized and standardized, thus using certain constant mixed recipes always the same and guaranteed strengths and properties arise in the end products, regardless of whether it is Rammed earth, clay blocks, mortar or plaster.
Der Erfindung liegt die Aufgabe zugrunde, natürliche Grund- Baustoffe aus Lehmböden mit oder ohne Zuschlagstoffe zu schaf fen, die lediglich an der Baustelle mit Wasser und entsprechend einem bestimmten Mischrezept mit Zuschlagstoffen vermischt werden müssen, um Baustoffe mit garantierten Festigkeiten zu ergeben.The invention has for its object natural To create building materials from clay soils with or without additives fen, only at the construction site with water and accordingly mixed with additives in a specific mixing recipe have to be to build materials with guaranteed strength surrender.
Gelöst wird diese Aufgabe nach dem erfindungsgemäßen Verfahren durch eine erste Zerkleinerung des Rohlehmbodens in einem Walzenbrecher bis auf 10 bis 20 mm Korngröße, eine zweite Zer kleinerung des Zerkleinerungsguts in einem weiteren Walzenbrecher bis auf 0 bis 4 mm Korngröße, eine Trocknung des zweiten Zerklei nerungsguts bei ca. 200°C in einem Drehrohrofen (Trieblextrockner, Drehzugtrockner) mit 800°C Flammentemperatur und eine Feinzer mahlung des Trocknungsguts zu Mehl oder Pulver in einer Walzen schüsselmühle, die mit einem Nachtrockner kombiniert ist, bis auf ca. 0,063-0,090 mm Korngröße und 1-2% Restfeuchte.This object is achieved by the method according to the invention by first crushing the raw clay floor in one Roll crusher up to 10 to 20 mm grain size, a second cer reduction of the size of the shredded material in another roll crusher up to 0 to 4 mm grain size, drying of the second pulp at a temperature of approx. 200 ° C in a rotary kiln (Trieblex dryer, Rotary dryer) with 800 ° C flame temperature and a finer grinding of the drying goods into flour or powder in a roller bowl mill, which is combined with a night dryer, except 0.063-0.090 mm grain size and 1-2% residual moisture.
Diesem Lehmpulver können nach seiner Herstellung geeignete faserige Zuschlagstoffe bzw. Füllmaterial, Sand u. a. m. zugegeben werden, wonach diese genau definierten Lehmpulvermischungen in Säcken verpackt oder in Transportsilos zur Baustelle transportiert wer den können, wo lediglich eine Wasserzumischung erfolgt. Bei der Vermischung mit Wasser können selbstverständlich noch weitere Zu schlagstoffe und Sand zugemischt werden, wenn das angelie ferte Lehmpulver diese Zuschlagstoffe noch nicht enthält.This clay powder can be suitable fibrous after its production Aggregates or filling material, sand and. a. m. be admitted after which these precisely defined clay powder mixtures in sacks packed or transported in transport silos to the construction site can where only water is added. In the Mixing with water can of course also be used Impact and sand are added when the angelie clay powder does not contain these additives.
Fertiggemischte, die nötigen Zuschlagstoffe im richtigen Ver hältnis enthaltende Lehmpulver, die an der Baustelle lediglich noch einer Wasserzugabe bedürfen, ersparen die lästige Misch arbeit an der Baustelle und vereinfachen die Herstellarbeit wesentlich, so daß sie im Einsatz bevorzugt sind.Ready mixed, the necessary additives in the correct ver clay powder containing ratio, which at the construction site only still need to be added water, save the annoying mixing work on the construction site and simplify the manufacturing work essential, so that they are preferred in use.
Das beschriebene Rohlehmverarbeitungsverfahren gibt dem Grund- Baustoff Lehm einheitliche Ausgangseigenschaften, die dem Endprodukt unter Anwendung der jeweiligen Mischrezeptur auch bestimmte gewünschte Endeigenschaften geben.The raw clay processing method described gives the basic Building material clay uniform starting properties that the End product using the respective mixing recipe too give certain desired final properties.
Gegenüber dem vergleichbaren Bindemittel in Form von Zement hat das beschriebene Lehmpulver-Bindemittel den Vorteil, daß seine Herstellung wegen des Fortfalls der Zementbrennung wesentlich energieärmer vonstatten geht, was in ökologischer Hinsicht vor teilhaft ist.Compared to the comparable binder in the form of cement the clay powder binder described has the advantage that its Manufacturing essential due to the elimination of cement burning less energy is what happens in ecological terms is partaking.
