Abstract

Mortar mixt. for cladding pipes and shaped articles consists of a mixt. of cement, e.g., 40 wt.%, quartz sand, e.g., 40 wt.%, and water, to which up to 1%, pref. 0.3-0.5 wt.% w.r.t. the finished mixt. of a granular foaming agent is added. The material is obtd. by milling polystyrene waste to grain sizes predominantly of 1-4mm. ADVANTAGE - Wt. redn., impact resistance.

Description

Umhüllungen dieser Art sind allgemein bekannt. Sie haben die Aufgabe, die Rohre gegen Korrosionseinflüsse des Bodens oder auch gegen mechanische Beschädigungen zu schützen. Als Beispiel für eine solche Rohrumhüllung und ihre Funktion wird die DE-PS 27 43 259 bzw. DD 2 44 973 genannt.Wraps of this type are generally known. Your job is to do the pipes against corrosion influences of the floor or also against mechanical To protect damage. As an example of such a pipe casing and its Function is called DE-PS 27 43 259 or DD 2 44 973.

Zementmörtelumhüllungen der genannten Art erhöhen das Gewicht der Metallrohre oder -formstücke beträchtlich. Bei Umhüllungen mit einer Schichtdicke von 5 mm kann die Gewichtszunahme je nach Nennweite des Teiles zwischen 10% und 33% liegen. Hierdurch wird die Handhabung schwieriger. Auch die gewichtsabhängige Ladekapazität der Transportfahrzeuge nimmt ab.Cement mortar coatings of the type mentioned increase the weight of the metal pipes or fittings considerably. For coatings with a layer thickness of 5 mm the weight gain can vary between 10% and 33% depending on the nominal size of the part lie. This makes handling more difficult. Even the weight-dependent The loading capacity of the transport vehicles is decreasing.

Der Erfindung lag die Aufgabe zugrunde, eine Mörtelmischung für die Umhüllung von Rohren oder Formstücken zu schaffen, die bei etwa gleicher Wirksamkeit eine deutliche Gewichtsminderung bringt. Zusätzlich soll die Sprödbruchempfindlichkeit der Umhüllung bei mechanischer Beanspruchung, etwa bei Schlag- und Stoßbeanspruchung, verringert werden.The invention was based on the object of a mortar mixture for the casing of pipes or fittings to create a with approximately the same effectiveness brings significant weight reduction. In addition, the brittle fracture sensitivity the sheathing under mechanical stress, such as impact and Impact stress, can be reduced.

Die erfindungsgemäße Mischung besitzt das im Kennzeichen des Patentanspruches 1 genannte Merkmal.The mixture according to the invention has this in the characteristic of Claim 1 mentioned feature.

Schaumstoffe auf Polystyrolbasis, auch als Styropor bekannt, finden eine vielseitige Anwendung. Neben der hervorragenden Wärmedämmung ist insbesondere das sehr geringe spezifische Gewicht von Bedeutung. Für Sonderzwecke kann man ein Schaumstoffgranulat herstellen, was jedoch recht teuer ist. Für den vorliegenden Verwendungszweck empfiehlt sich jedoch ein granulatähnliches Mahlgut aus Styroporabfällen, zumal die Entsorgung dieser Abfälle große Probleme bereitet. Bei dem Mahlen der Abfälle entstehen dann Styroporpartikel mit einer Korngröße bis 7 mm, wobei aber kleinere Korngrößen zwischen 1 und 4 mm überwiegen.Polystyrene-based foams, also known as styrofoam, are versatile  Application. In addition to the excellent thermal insulation, this is particularly great low specific weight important. For special purposes, one can Produce foam granules, but this is quite expensive. For the present However, a granulate-like regrind is recommended Styrofoam waste, especially since the disposal of this waste causes great problems. At The grinding of the waste then creates polystyrene particles with a grain size up to 7 mm, but smaller grain sizes between 1 and 4 mm predominate.

Dieses granulatähnliche Schaumstoffmaterial soll der Mörtelmischung beigemischt werden, und zwar selbstverständlich nur in solchen Mengen, daß die eigentliche Funktion der Mörtelmischung nicht beeinträchtigt wird. Dabei ist der Anteil je nach Verwendungszweck variabel. Wesentlich ist eine möglichst homogene Durchmischung im trockenen Zustand.This granulate-like foam material should be added to the mortar mixture become, and of course only in such quantities that the actual Function of the mortar mixture is not affected. The proportion depends on Intended use variable. It is essential to be as homogeneous as possible Mix in the dry state.

Durch die Beimischung des Schaumstoffmaterials erfolgt eine starke Gewichtsverringerung der Zementmörtelumhüllung. Man kann Umhüllungen mit gleicher Schichtdicke aber geringerem Gewicht oder mit größerer Schichtdicke und gleichem Gewicht bezogen auf die bisher üblichen Mörtelmischungen erzeugen.The admixture of the foam material creates a strong one Weight reduction of the cement mortar coating. You can use wrappings with same layer thickness but less weight or with greater layer thickness and produce the same weight based on the previously used mortar mixtures.

Die Mörtelmischung mit dem Zusatz kann wie üblich gegossen, angeschleudert, extrudiert und bei bestimmten Düsenquerschnitten auch gespritzt werden. Ein besonderer Vorteil neben der Gewichtseinsparung ist auch der Abbau der Sprödbruchempfindlichkeit der Umhüllung bei mechanischer Beanspruchung. Die Umhüllung ist bei Schlag- und Stoßbeanspruchung weniger empfindlich als die bisher bekannten Mörtelumhüllungen.The mortar mixture with the additive can be poured, centrifuged as usual, extruded and also injected with certain nozzle cross-sections. A In addition to saving weight, a particular advantage is the reduction of The cladding is susceptible to brittle fracture when subjected to mechanical stress. The Sheathing is less sensitive than that to impact and shock loads previously known mortar coatings.

Die folgende Gegenüberstellung einer herkömmlichen Mischung mit der erfindungsgemäßen Mischung belegt vorstehende Angaben:The following comparison of a conventional mixture with the The mixture according to the invention supports the above information:

Eine Mischung mit je 40,0 Gew.-% Zement und Quarzsand und 20 Gew.-% Wasser besitzt eine Dichte von 2,06/cm3. Werden der Mischung jedoch bei den sonst gleichen Verhältnissen etwa 0,4% des granulatähnlichen Schaumstoffmaterials beigemischt, dann liegt die Dichte bei nur 1,36/cm3. Als bevorzugter Gewichtsanteil sind deshalb 0,3- 0,5% anzusehen.A mixture with 40.0% by weight of cement and quartz sand and 20% by weight of water has a density of 2.06 / cm 3 . However, if about 0.4% of the granulate-like foam material is added to the mixture at the otherwise identical ratios, the density is only 1.36 / cm 3 . 0.3-0.5% should therefore be regarded as the preferred proportion by weight.
