Optimierte Betonzusammensetzung beim Leichtbeton mit geschlossenem Gefüge

Abstract: Europaweit gewinnt Leichtbeton wieder an Bedeutung. Die Weiterentwicklung in der Betontechnologie zur Bewältigung neuer Bauaufgaben, wie z. B. schwimmende Plattformen zur Ölförderung, führte zu Betonen, deren Rohdichte im Grenzbereich zwischen Normalbeton und Leichtbeton liegt. Zu ihrer Herstellung wird ein Gemisch aus dichtem Normalzuschlag und Leichtzuschlag verwendet. Seine im Vergleich zu Normalzuschlag höheren Kosten machen Überlegungen zur Optimierung der Betonzusammensetzung notwendig und zwingen zu ein… Show more

“…With regard to sustainable building, UHPLC will certainly be increasingly used in the future due to its multifunctional capability. According to Grübel [4], a concrete with a light aggregate and a cement paste matrix strength of > 90 N/mm² fails by so-called grain fracture. In this case, the grains break and no longer participate in the load transfer, which ultimately leads to the failure of the entire system.…”

“…For many specimens, the fracture pattern can only be seen in the final state because no cracks or defective structures were recorded in the last image before failure. Defective structures would be, for example, broken expanded glass, which fails like described in [4]. However, the specimens either withstood the load without damage or failed because the load was too close to the failure limit.…”
