Abstract

Sprayable mixture for a pigmented concrete surface finish contains water, Repacryl hellgrau(RTM: binder), Grundier-konzentrat LF 938(RTM: concrete primer), ZEM III/A 32.5(RTM: cement; for concrete surface effect), Isola VZ 2(RTM: retarder) and black oxide pigment in the wt. ratios 1:0.5:0.5:0.5:0.1:0.01.

Description

Die Oberflächenveredlung bei nicht ereichter Sichtbetonqualität erfolgt zurzeit durch:The surface refinement at not reached Architectural concrete is currently carried out by:

  • a) Aufbringen eines zementgebundenen Putzes odera) Applying a cement-bound plaster or
  • b) Aufbringen eines zementgebundenen Betonspachtels bzw.b) applying a cement-bound concrete spatula or
  • c) Aufbringen eines deckenden Farbanstriches (handelsübliche Farben)c) Applying a covering coat of paint (standard colors)

Alle oben genannten Verfahren sind sehr kosten- und zeitintensiv und erreichen im Endzustand zum Teil nicht den vom Architekten geplanten optischen Gesamteindruck des Bauwerkes.All of the above procedures are very costly and time-consuming and sometimes achieve in the final state not the overall visual impression planned by the architect Building.

Durch das im Schutzanspruch 1 eingesetzte Material wird im Spritzverfahren eine kosten- und zeitgünstige Lösung erzielt. Gleichzeitig wird der optische Eindruck von einer erreichten Sichtbetonqualität erfüllt.By the used in protection claim 1 Material is achieved in a cost-effective and time-saving solution by spraying. simultaneously the visual impression of achieved architectural concrete quality is fulfilled.

Das im Schutzanspruch 1 eingesetzte Material wurde bereits am Bauvorhaben Modernisierung und Instandsetzung Olympiastadion Berlin an den Außenbauteilen Tiefgarage Süd mit VIP-Vorfahrt im Spritzverfahren eingesetzt.The one used in protection claim 1 Material has already been modernized and repaired on the construction project Olympiastadion Berlin on the external components Underground car park south used with VIP right of way in the spray process.

An diesem Bauvorhaben wurde die geforderte Sichtbetonqualität durch folgende Faktoren nicht erfüllt:The required on this construction project Architectural concrete not fulfilled by the following factors:

  • – Erhebliche Farbunterschiede der Betonansichtsfläche (Wolkenbildung)- Significant Color differences of the concrete face (cloud formation)
  • – Abplatzungen bzw. Ausblühungen an den Schalungsstößen bzw. Arbeitsfugen- flaking or efflorescence at the formwork joints or construction joints
  • – Abplatzungen bzw. Ausblühungen an den Ankerstellen- flaking or efflorescence at the anchor points

Bedingt durch oben genannte Mängel erfolgte seitens des Auftraggebers und der Architekten keine Abnahme. Nach erfolgter Beseitigung der Betonschäden (Abplatzungen und Ausblühungen) erfolgte das Aufbringen des im Schutzanspruch 1 genannten Materials im Spritzverfahren. Es wurden ca. 20.000 m2 Sichtbetonflächen nachbehandelt.Due to the above-mentioned defects, the client and the architects did not accept the goods. After the concrete damage (flaking and efflorescence) had been eliminated, the material mentioned in protection claim 1 was applied by spraying. Approx. 20,000 m 2 of exposed concrete surfaces were treated.

Durch die farbpigmentierte Betonoberflächenveredlung nach Schutzanspruch 1 konnte der Betoncharakter der Betonoberfläche erhalten bleiben. Je nach Dosierung der Farbpigmente kann ein gewünschter Farbton erreicht werden. Der Gesamteindruck des Bauwerkes entsprach den Anforderungen des Auftraggebers und des Architekten.Through the color pigmented concrete surface finishing according to protection claim 1, the concrete character of the concrete surface could be preserved stay. Depending on the dosage of the color pigments, a desired one Hue can be achieved. The overall impression of the building corresponded the requirements of the client and the architect.
