Abstract

Plastic fibres. for use as additives to concrete or mortar in building materials, are held in water-soluble bags which dissolve during the mixing with the concrete or mortar. The bags are pref. polyvinylalcohol; the fibres concerned are preferably polypropylene, polyethylene, acrylipnitrile of insoluble polyvinylalcohol. The fibres used are produced by shredding plastic films; to minimise the volume of the bags when filled with the fibres the bags are made porous, e.g. by perforating. Alternatively the bags can be intermittently welded o sewn. They can be made in different sizes so that different quantities of fibres can be utilised. Bags containing the fibres are mixed with the appropriate quantity of e.g. concrete for example in a 30 tonnes travelling mixer taking 6 cu.m mix. This mixing requires some 6 mins. The necessary polyvinylalcohol bags take only max. 1 min. to be added and dispersed. ADVANTAGE - The fibres used are easily handled during mixing. They can be accurately measured out.

Description

Die Erfindung betrifft Fasern aus Kunststoff als Bauzu­ schlagstoffe zur Beimischung zu Beton oder Mörtel.The invention relates to plastic fibers as Bauzu Impact agents for adding to concrete or mortar.

Derartige Fasern werden in letzter Zeit als Bauzu­ schlagstoffe verwendet, um eine Schwindrißbildung im Mörtel oder Beton zu verhindern, die H2O-Durchlässig­ keit zu vermindern und den Widerstand gegen Erschütte­ rung sowie die Druck-, Spaltzug- und Biegefestigkeit zu erhöhen. Die Fasern können als Multifil ausgebildet sein oder durch Schneiden von Kunststoffolien herge­ stellt werden. Sie werden in Behälter verpackt und der Anwender entnimmt dem Behälter die für seine Beton- bzw. Mörtelmischung notwendige Menge an Kunststoffasern und fügt sie dem Gemisch hinzu, das weiterbewegt wird bis die Fasern gleichmäßig in dem Gemisch verteilt sind. Such fibers have recently been used as building materials to prevent shrinkage cracking in the mortar or concrete, to reduce the H 2 O permeability and to increase resistance to shock and pressure, splitting and bending strength. The fibers can be designed as a multifilament or can be produced by cutting plastic films. They are packed in containers and the user takes from the container the amount of plastic fibers required for his concrete or mortar mixture and adds them to the mixture, which is moved on until the fibers are evenly distributed in the mixture.

Dieser Vorgang ist umständlich, da die Fasern erst dem Behälter entnommen werden müssen, wodurch sie verschüt­ tet werden können und wobei die Dosierung für das Be­ ton- bzw. Mörtelgemisch nicht immer richtig eingehalten wird.This process is cumbersome because the fibers are only there Containers must be removed, which spills them can be tet and the dosage for the loading clay or mortar mixture not always correctly observed becomes.

Aus der DE 31 46 261 A1 ist ein faserförmiger Zuschlag für Beton oder Mörtel bekannt, der aus einer Faser oder einem Faserbündel und einem mit diesem verbundenen Kör­ per besteht. Mehrere Körper und Fasern werden zu einem Ring ausgebildet und mit dem Beton oder Mörtel ver­ mischt, wodurch eine gleichmäßige Einbindung unter Ver­ meidung einer "Igelbildung" von Faserbündeln in das Baumaterial erfolgen soll.DE 31 46 261 A1 describes a fibrous additive known for concrete or mortar made from a fiber or a fiber bundle and a body connected to it per exists. Multiple bodies and fibers become one Ring formed and ver with the concrete or mortar mixes, whereby a uniform integration under Ver avoidance of "hedgehog formation" of fiber bundles in the Construction material is to be made.

Das Derwent-Kurzreferat 83-779 453/40 beschreibt ein wärmeisolierendes Element, bei dem Fasern unter Vakuum in Kunststoffbeutel eingeschweißt werden.Derwent abstract 83-779 453/40 describes one heat-insulating element in which fibers under vacuum be sealed in plastic bags.

Der Erfindung liegt somit die Aufgabe zugrunde, Fasern als Bauzuschlagstoffe vorzusehen, die eine einfache Handhabung beim Mischvorgang und eine genaue Dosierung entsprechend der Beton- bzw. Mörtelmenge ermöglichen.The invention is therefore based on the object of fibers to be provided as building aggregates, which is a simple Handling during the mixing process and an exact dosage allow according to the amount of concrete or mortar.

Diese Aufgabe wird erfindungsgemäß durch die kennzeich­ nenden Merkmale des Hauptanspruchs gelöst.This object is inventively characterized by resolved characteristics of the main claim.

Dadurch, daß die Fasern aus Kunststoff in jeweils einem wasserlöslichen Kunststoffbeutel aufgenommen sind, der sich während des Mischvorgangs des Betons oder des Mör­ tels auflöst, kann der Mischvorgang stark vereinfacht werden, da lediglich der Kunststoffbeutel in den Mi­ scher gegeben werden kann. Dabei sind vorteilhafterwei­ se die Beutel für unterschiedliche Mengen von Fasern ausgelegt, damit eine schnelle Dosierung entsprechend den gewünschten Beton- bzw. Mörtelmengen durchgeführt werden kann. Da sich der Kunststoffbeutel vollständig auflöst, verbleibt kein Abfall, der entsorgt werden müßte.The fact that the plastic fibers in one water-soluble plastic bags are included, the during the mixing process of the concrete or mortar dissolves, the mixing process can be greatly simplified because only the plastic bag in the Mi can be given. Here are advantageous se the bags for different amounts of fibers designed so that a quick dosage accordingly  the desired amount of concrete or mortar can be. Because the plastic bag completely dissolves, there is no waste left to be disposed of ought to.

Vorteilhafterweise ist der Kunststoffbeutel luftdurch­ lässig verschlossen, damit die Beutel nicht zusätzliche Luft einschließen, wodurch die Beutel mit den Fasern raumaufwendiger werden würden. Eine kostengünstige Lö­ sung für die Durchlässigkeit besteht darin, daß die Kunststoffbeutel intermittierend verschweißt sind. The plastic bag is advantageously air-permeable casually closed so that the bags are not additional Include air, creating the bags with the fibers would take up more space. An inexpensive Lö Solution for the permeability is that the Plastic bags are welded intermittently.  

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird in der nachfolgenden Beschreibung näher erläutert. Die einzige Figur zeigt einen die Fasern enthaltenden Kunststoffbeutel nach der Erfindung.An embodiment of the invention is in the Drawing shown and is in the following Description explained in more detail. The only figure shows a plastic bag containing the fibers the invention.

In der Figur sind mit 1 die Fasern bezeichnet, die in einem Kunststoffbeutel 2 zusammengefaßt sind. Die Fasern 1 bestehen aus einem Polypropylen, Polyäthy­ len, Polyacrylnitril, nicht löslichem PVAL oder der­ gleichen Kunststoffe und sie werden durch Zerschnei­ den von Folien oder als Multifil hergestellt. Der Kunststoffbeutel 2 ist wasserlöslich und kann aus jedem wasserlöslichen Kunststoff hergestellt werden, wobei beispielsweise Polyvenylalkohol anwendbar ist. Um den benötigten Lager- und Transportraum der mit Fasern gefüllten Kunststoffbeutel zu minimieren, sind die Kunststoffbeutel 2 luftdurchlässig. Die Luft­ durchlässigkeit kann durch Perforieren der Kunst­ stoffbeutel realisiert werden. Weniger aufwendig und somit kostengünstiger ist jedoch, wenn die Kunst­ stoffbeutel 2 luftdurchlässig verschlossen werden. Beispielsweise können die Beutel 2 intermittierend verschweißt werden, was in der Figur durch die Schweißnaht 3 angedeutet ist. In einer anderen Aus­ führungsform kann der Kunststoffbeutel 2 vernäht wer­ den.In the figure, 1 denotes the fibers, which are combined in a plastic bag 2 . The fibers 1 consist of a polypropylene, Polyäthy len, polyacrylonitrile, non-soluble PVAL or the same plastics and they are made by cutting the foils or as a multifilament. The plastic bag 2 is water-soluble and can be made from any water-soluble plastic, polyvenyl alcohol being applicable, for example. In order to minimize the storage and transport space required for the plastic bags filled with fibers, the plastic bags 2 are permeable to air. The air permeability can be achieved by perforating the plastic bag. However, it is less complex and therefore more cost-effective if the plastic bags 2 are closed in an air-permeable manner. For example, the bags 2 can be welded intermittently, which is indicated in the figure by the weld seam 3 . In another embodiment, the plastic bag 2 can be sewn to who.

Die Kunststoffbeutel 2 können in unterschiedlichen Größen vorgesehen werden, damit unterschiedliche Do­ siermengen von Fasern 1 aufgenommen werden können. Diese Fasermengen sind an die üblicherweise im Handel vorhandenen Mischvorrichtungen für Mörtel oder Beton angepaßt, so daß nur die gewünschte Anzahl von Kunst­ stoffbeuteln bzw. die gewünschte Dosiermenge verwandt werden muß.The plastic bags 2 can be provided in different sizes so that different dosages of fibers 1 can be added. These amounts of fiber are adapted to the mixing devices for mortar or concrete that are usually commercially available, so that only the desired number of plastic bags or the desired metering amount must be used.

Zur Herstellung des Gemisches aus Mörtel bzw. Beton und Fasern 1 werden der oder die Kunststoffbeutel mit der benötigten Dosiermenge dem Mörtel bzw. Betonge­ misch hinzugefügt, der oder die Kunststoffbeutel 2 lösen sich in dem wasserhaltigen Gemisch auf, so daß die Fasern 1 freikommen und im weiteren Mischvorgang gleichmäßig verteilt werden.To produce the mixture of mortar or concrete and fibers 1 , the plastic bag (s) with the required dosage is added to the mortar or concrete mix, the plastic bag (s ) 2 dissolve in the water-containing mixture, so that the fibers 1 are released and in further mixing process can be evenly distributed.

Als Beispiel wurde ein Gemisch aus Beton oder Mörtel und Fasern in einem 30-Tonnen-Fahrmischer, der 6 Ku­ bikmeter an Beton- bzw. Mörtelgemisch umfaßt, durch­ geführt. Üblicherweise beträgt die Mischzeit eines derartigen Fahrmischers sechs Minuten bei 1 Min/m3. Der Polyvenylalkohol-Kunststoffbeutel 2 mit der für 6 Kubikmeter gewünschten Dosiermenge an Fasern 1 wurde zu der Mischung hin zugefügt, wobei er sich in weni­ ger als einer Minute aufgelöst hat. Die Verteilung der Fasern nach der üblichen Mischzeit war sehr zu­ friedenstellend.As an example, a mixture of concrete or mortar and fibers was carried out in a 30-ton truck mixer, which comprises 6 cubic meters of concrete or mortar mixture. The mixing time of such a truck mixer is usually six minutes at 1 min / m 3 . The polyvinyl alcohol plastic bag 2 with the desired amount of fibers 1 for 6 cubic meters was added to the mixture, whereby it dissolved in less than a minute. The distribution of the fibers after the usual mixing time was very satisfactory.
