Description
Die Erfindung betrifft ein Papier zur Herstellung von Waschbeton, das partiell mit einem mit dem Beton in Berührung kommenden Abbindeverzögerer beschichtet ist.The invention relates to a paper for the production of exposed aggregate concrete, which is partially with a with the concrete in Contact coming setting retarder is coated.
Bei einem solchen aus der DE-OS 20 20 339 bekannten Papier hat sich gezeigt, daß es während des Abbindens der vcrr dem Papier entfernteren Beton-Schicht häufig von der Betonoberfläche stellenweise abhebt, so daß ein gleichmäßiges Eindringen des Abbindeverzögerer in die obere Betonschicht nicht gewährleistet ist Dies führt zu ungleichmäßigen und unschönen Waschbetonoberflächen. Besonders unangenehm macht sich eine nicht vollfläciiige Anlage des Papiers dann bemerkbar, wenn das Papier nur Stellenweise mit Abbindeverzögerern beschichtet ist, um hierdurch ausgewaschene und unbearbeitete Beton- ©berflächenteile in einem bestimmten Muster zu erhalten. Ein nicht exaktes Anhaften des Papiers führt •n den Grenzlinien zwischen iuisgewi ..dienen und nicht bearbeiteten Oberflächenteiler, zu ungenauen und verschwommenen Übergängen. Darüt r hinaus haften die nicht mit Verzögerer beschichteten Papierflächen an der Betonoberfläche derart fest, daß sie nur durch eine zusätzliche zeitraubende Bearbeitung entfernt werden können.In such a paper known from DE-OS 20 20 339 it has been shown that it is during the Setting of the concrete layer further away from the paper often from the concrete surface in places lifts off so that the setting retarder does not penetrate evenly into the upper concrete layer This leads to uneven and unsightly exposed aggregate concrete surfaces. Particularly uncomfortable makes a not full-area system of the Paper is noticeable when the paper is only coated with setting retarders in places, in order to thereby wash out and unprocessed concrete surface parts in a certain pattern obtain. Imprecise adhesion of the paper leads to the boundary lines between iuisgewi .. serving and not machined surface dividers, too imprecise and blurry transitions. Stick to it the paper surfaces not coated with retarder the concrete surface so firmly that they can only be removed by additional time-consuming processing can.
Der Erfindung liegt die Aufgabe zugrunde, ein Papier der eingangs genannten Gattung zu schaffen, das sich während der Auflage auf der Betonoberfläche von dieser nicht, abhebt.The invention is based on the object of creating a paper of the type mentioned at the outset, which does not lift off from the concrete surface while it is resting on it.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Papier auf beiden Seiten mit Kunststoff beschichtet ist.According to the invention, this object is achieved in that the paper is covered with plastic on both sides is coated.
ίο Ein derartiges partiell mit einer Abbindeverzögwerschicht versehenes Papier bleibt frei von Spannungen und Wellungen vollflächig an der Betonoberfläche haften, so daß der Verzögerer gleichmäßig in den Beton eindringt. Ferner entstehen exakte Grenzen zwischen ausgewaschenen und unbearbeiteten Betonoberflächenteil°n. Auch die nicht mit Verzögerer versehenen Papierflächen lassen sich nach dem Abbinden leicht von der Betonoberfläche abziehen.ίο One of these partially with a setting delay layer provided paper remains free of tension and corrugations over the entire surface of the concrete surface adhere so that the retarder penetrates evenly into the concrete. Furthermore, there are exact boundaries between washed out and unprocessed concrete surface part ° n. Even the paper surfaces not provided with retarder can easily be removed after they have set peel off the concrete surface.
Als besonders vorteilhafter Kunststoff hat sich Polyäthylen erwiesen.Polyethylene has proven to be a particularly advantageous plastic.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in einem Ausschnitt dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing in a section and is in described in more detail below.
Ein Papier 1 mit einer Fläche in der Größe der Oberfläche des Waschbetonsteins und einem Gewicht von 110 g/m2 ist beidseitig mit einer eine glänzende Oberfläche aufweisenden Polyäthylenschicht 2a, 2b in einer Dicke von 20 g/m2 beschichtet. Zumindest diejenige Polyäthylenschicht 2b, die den Abbindeverzögerer 3 aufnehmen soll, kann zur Verbesserung der Benetzbarkeit an ihrer Oberfläche mit physikalischen oder chemischen Mitteln, z. B. einer Hochfrequenzentladung, behandelt sein. Auf diese Polyäthylenschicht 2b ist der auf nicht wäßriger Basis aufgebaute Abbindeverzögerer 3 partiell in einer Dicke von 65—70 g/m2 aufgetragen. Die Verzögererschicht besteht aus dem Verzögerer und einem Füllstoff, welcher in Form einer organisches Lösungsmittel enthaltenden Paste aufgebracht istA paper 1 with an area the size of the surface of the exposed aggregate concrete block and a weight of 110 g / m 2 is coated on both sides with a glossy surface polyethylene layer 2a, 2b to a thickness of 20 g / m 2 . At least that polyethylene layer 2b, which is to receive the setting retarder 3, can be used to improve the wettability of its surface with physical or chemical means, eg. B. a high frequency discharge to be treated. The non-aqueous setting retarder 3 is partially applied to this polyethylene layer 2b in a thickness of 65-70 g / m 2. The retarder layer consists of the retarder and a filler, which is applied in the form of a paste containing organic solvent
