Title:	Statistische Bewertung der Druckfestigkeit von ultrahochfestem Beton (UHFB)
Abstract:	Ultrahochleistungsbetone weisen eine Vielzahl von Vorteilen gegenüber normalfesten Betonen auf, z. B. ein extrem dichtes Gefüge, sehr hohe Festigkeiten und exzellente Eigenschaften in Bezug auf die Dauerhaftigkeit. Für eine sichere und zuverlässige Bemessung von Bauteilen aus Ultrahochleistungsbetonen in den Grenzzuständen der Tragfähigkeit und Gebrauchstauglichkeit muss die rechnerisch anzusetzende Druckfestigkeit und deren Streuung bekannt sein. Dazu wurden Ergebnisse aus Druckfestigkeitsprüfungen in einer Datenbank zusammengestellt und statistisch ausgewertet. Statistical evaluation of compressive strength of ultra-high strength concrete Compared to normal strength concrete, ultra-high strength concrete has many advantageous properties such as extreme compact microstructure, very high compressive strength and enhanced properties with regard to durability. For a reliable design of ultra-high strength concrete components in ultimate and serviceability limit states, the characteristic compressive strength and the scattering of the compressive strength must be known. For this aim, compressive tests have been compiled in a database and analysed statistically.
