In Verbindung mit dem BAW-Merkblatt und der DIN SPEC 91167 dient diese Pr\u00fcfung der G\u00fcte\u00fcberwachung im Bauwesen. Ermittelt wird die Widerstandsf\u00e4higkeit der Betonoberfl\u00e4che gegen\u00fcber witterungsbedingtem Masseverlust. Betonbauwerke unterliegen im Winter einer starken Beanspruchung durch kapillares Saugen von Tausalzl\u00f6sungen und anschlie\u00dfende Frostphasen.<\/p><p>Die exakte Auswertung des CDF-Tests erfordert die vollst\u00e4ndige Abl\u00f6sung der durch Frost gel\u00f6sten Betonpartikel von der Probenoberfl\u00e4che.

Die Hochleistungs-Ultraschallb\u00e4der von BANDELIN liefern die geforderte Arbeitsfrequenz und Kavitationsleistung, um diese Partikel normkonform vom Pr\u00fcfk\u00f6rper zu trennen.

Pr\u00fcfzyklus auf exakt 28 Frost-Tau-Wechsel. Nach dieser standardisierten Belastungsphase in einer dreiprozentigen Natriumchloridl\u00f6sung sammeln sich lose Partikel an der Probenoberfl\u00e4che. Diese Bestandteile m\u00fcssen f\u00fcr eine korrekte Analyse vollst\u00e4ndig entfernt und gewogen werden. Mechanische Verfahren besch\u00e4digen das intakte Betongef\u00fcge und verf\u00e4lschen den ermittelten Masseverlust. Die Pr\u00fcfrichtlinien fordern daher die Verwendung von Ultraschall, um die abgewitterten Bestandteile ber\u00fchrungslos abzul\u00f6sen.<\/p><p>Das Ultraschallbad wird f\u00fcr diese indirekte Beschallung mit Leitungswasser bef\u00fcllt. Um die Oberfl\u00e4chenspannung des Wassers zu senken und die Entgasung zu beschleunigen, werden tensidhaltige Pr\u00e4parate wie beispielsweise TICKOPUR R 33 zugesetzt. Das Gemisch fungiert hierbei als reines Koppelmedium. Die Ultraschallwellen durchdringen diese Koppelfl\u00fcssigkeit und die Wandung des Edelstahl-Pr\u00fcfgef\u00e4\u00dfes nahezu verlustfrei. Die f\u00fcr die Partikelabl\u00f6sung verantwortliche Kavitation entsteht im Inneren des Gef\u00e4\u00dfes, direkt in der Pr\u00fcfl\u00f6sung an der Oberfl\u00e4che der Betonprobe.
