Abstract

Self-sealing concrete (Conflex (SVB)) has a concrete grain size according to DIN 1045 and comprises Portland cement, hard coal fly ash, a concrete liquefier, a flux additive and an accelerator.

Description

BeschreibungDescription

Beton „CONFLEX (SVB)"Concrete "CONFLEX (SVB)"

Dieser besondere Beton wird als Transportbeton oder Rezeptbeton für Betonwaren und Betonfertigteile, auch für Stahlbeton, in Betonmischanlagen für Frischbeton und in Werksmischanlagen von Betonwaren- und Betonfertigteilwerken hergestellt. Dazu werden die einzelnen Komponenten gravimetrisch bzw. volumetrisch dosiert und im Betonmischer bis zur völligen Homogenität vermischt.This special concrete is produced as ready-mixed concrete or recipe concrete for concrete products and precast concrete parts, including reinforced concrete, in concrete mixing plants for fresh concrete and in factory mixing plants in concrete product and precast concrete plants. The individual components are dosed gravimetrically or volumetrically and mixed in the concrete mixer until they are completely homogeneous.

Er wird als Beton BII nach DIN 1045 bzw. Beton nach DIN EN 206-12/DIN 1045-2 hergestellt und als Beton BII nach DIN 1045 bzw. Beton der Überwachungsklasse 2 nach DIN 1045-3 verarbeitet.It is produced as concrete BII according to DIN 1045 or concrete according to DIN EN 206-12/DIN 1045-2 and processed as concrete BII according to DIN 1045 or concrete of monitoring class 2 according to DIN 1045-3.

Stand der Technik ist, dass herkömmlicher Beton unter Einwirkung von zusätzlicher Verdichtungsenergie in Schalungen eingebaut werden muss, um alle Hohlräume zu füllen und eine gleichmäßige Entlüftung zu gewährleisten. Dazu werden stationäre oder mobile Schwingungserzeuger oder Rüttler verwendet. Dies ist auch trotz Verwendung von üblichen Zusatzmitteln zur Betonverflüssigung notwendig.The current state of the art is that conventional concrete must be installed in formwork using additional compaction energy in order to fill all the cavities and ensure even ventilation. Stationary or mobile vibration generators or vibrators are used for this purpose. This is necessary even when using conventional additives to liquefy concrete.

Der selbstverdichtende Beton fließt aufgrund seiner besonderen Eigenschaften völlig ohne Einwirkung von zusätzlicher Verdichtungsenergie. Diese besonderen Eigenschaften werden durch seine besondere Zusammensetzung und seinen hohen Anteil an Mehlkorn (feinste Zuschlagstoff bestandteile) realisiert.Due to its special properties, self-compacting concrete flows without the need for additional compaction energy. These special properties are achieved through its special composition and its high proportion of fine grain (finest aggregate components).

Mit dem so hergestellten Beton lassen sich Festbetonoberflächen höchster Güte herstellen. Die Betonierzeit und die Lärmentwicklung an Betonarbeitsplätzen reduzieren sich wesentlich.The concrete produced in this way can be used to produce hardened concrete surfaces of the highest quality. The concreting time and noise levels at concrete workplaces are significantly reduced.
