Description
Verfahren zur Herstellung von Bauteilen des Ingenieurbaues, insbesondere von Straßendecken Die Erfindung betrifft ein Verfahren zur Herstellung von Bauteilen des Ingenieurbaus, insbesondere von Straßendecken, aus einem dem bekannten Zementbeton ähnlichen Baustoff.Process for the production of structural components, in particular of road surfaces The invention relates to a method for producing components of civil engineering, especially of road surfaces, made of one of the well-known cement concrete similar building material.
Die Herstellung solcher Bauteile aus Beton, der aus körnigen Gesteinsmengen (Kies, Sand, Splitt u. ä.), hydraulischen Bindemitteln, insbesondere Zement und Wasser besteht, ist bekannt. Bei der Verarbeitung dieser Einzelstoffe mußte bisher darauf geachtet werden, daß dem Beton Bestandteile bindiger Bodenarten (Lehm, Ton usw.) oder auch Humus ferngehalten wurden, um die bautechnischen Eigenschaften, z. B. die Festigkeit, des Bodens nicht zu verschlechtern.The production of such components from concrete, from granular amounts of rock (Gravel, sand, chippings, etc.), hydraulic binders, especially cement and It is well known that there is water. When processing these individual substances previously had to care must be taken that the concrete contains constituents of cohesive soil types (loam, clay etc.) or humus were kept away in order to preserve the structural properties, z. B. not to deteriorate the strength of the soil.
Andererseits ist im Straßenbauwesen bekannt, daß selbst gewisse bindige, aber im wesentlichen humusfreie Böden durch Zugabe von Zement und Wasser zur Herstellung von Straßendecken betonartig verfestigt werden können (Bodenvermörtelung).On the other hand, it is known in road construction that even certain cohesive, but essentially humus-free soils by adding cement and water for production can be solidified like concrete from road surfaces (soil reinforcement).
Es ist auch die Anwendung von kaustisch gebranntem Magnesit und Chlormagnesium in Verbindung mit Sand und Schotter zur Herstellung von Makadamstraßendecken, sogenanntem K-Beton, bzw. in Verbindung mit organischen Füllstoffen, wie z. B. Sägespäne, zur Herstellung von Steinholz bekannt.There is also the use of caustic magnesite and chlorine magnesium in connection with sand and gravel for the production of macadam road surfaces, so-called K-concrete, or in connection with organic fillers, such as. B. sawdust, for Production of stone wood known.
Bei vorliegender Erfindung besteht das Neue einmal darin, daß jeder, auch humushaltiger Erdboden in nicht aufbereitetem Zustand mit kaustisch gebranntem Magnesit, Magnesiumsalzlösungen und Wasser zu einer Mischung (Magnesitbodenbeton) verarbeitet wird, zum anderen in der neuen Erkenntnis, daß Magnesitbodenbeton neben hoher Festigkeit gleichzeitig eine hohe Elastizität besitzt. Es kann nach diesem Verfahren z. B. bei Herstellung von Straßendecken der unmittelbar anstehende Erdboden mit den übrigen Stoffen an Ort und Stelle in einem Mischgang verarbeitet werden. Das Herstellungsverfahren ist dadurch wesentlich vereinfacht. Auch können Dehnungsfugen, wie sie bei Betonstraßen sonst notwendig sind, infolge der hoben Elastizität -des Magnesitbodenbetons fortfallen.In the present invention, the novelty consists in the fact that everyone also humus-containing soil in an unprocessed state with caustic burnt Magnesite, magnesium salt solutions and water to form a mixture (magnesite floor concrete) is processed, on the other hand in the new knowledge that magnesite floor concrete next high strength at the same time has high elasticity. It can after this process z. B. in the production of road surfaces directly pending soil with the other substances in place in a mixed passage are processed. This significantly simplifies the manufacturing process. Expansion joints, as they are otherwise necessary on concrete roads, can also result the increased elasticity of the magnesite concrete floor.
Außerdem ist es möglich, durch Dosierung der Zusätze von kaustisch gebranntem Magnesit, der Magnesiumsalzlösungen und des Wassers die jeweils gewünschten bautechnischen Eigenschaften des Magnesitbodenbetons zu erreichen. Nach diesem einfachen Verfahren hergestellte Baukörper halten den üblichen Beanspruchungen auf Druckfestigkeit, Säurefestigkeit, Abnutzungswiderstand, Frost- und Wasserbeständigkeit usw. in unerwartet hohem Maße stand und besitzen große Elastizität.It is also possible to add caustic by dosing burnt magnesite, the magnesium salt solutions and the water as required to achieve structural properties of the magnesite floor concrete. After this simple one Structures manufactured using methods withstand the usual stresses on compressive strength, Acid resistance, abrasion resistance, frost and water resistance, etc. in unexpected to a high degree and have great elasticity.
Erforderlichenfalls können bei diesem Verfahren eine Änderung der Kornzusammensetzung des jeweils zu verarbeitenden Erdbodens durch Zusatz an sich bekannter physikalischer Mittel, z. B. Splitt, Kies, Sand usw., herbeigeführt und dadurch dem Magnesitbodenbeton noch bessere bautechnische Eigenschaften gegeben werden.If necessary, this procedure can be used to change the Grain composition of the soil to be processed in each case by the addition per se known physical means, e.g. B. grit, gravel, sand, etc., brought about and this gave the magnesite concrete floor even better structural properties will.
