Festigkeits- und Verformungseigenschaften von Beton als Bewertungskriterien von AKR-Performance-Prüfungen

Strength and deformation properties of concrete as evaluation criteria for ASR performance tests

Within the scope of the application procedure of the Materials Testing Institute University of Stuttgart (MPA University Stuttgart) as approved ASR consultant according to ARS 04/2013 [1] a comprehensive program of examinations was conducted at the MPA in Stuttgart and the Finger-Institute (FIB) in Weimar. The first part of the examinations was about to evaluate whether the ASR potential of concrete compositions is evaluated consistently at the MPA University Stuttgart and the FIB in Weimar by using the FIB cyclic climate storage test method as ASR performance test. For that purpose, a round-robin test with four different concrete compositions tested under exposure of water and NaCl solution respectively was done. The second part of the examinations was about to characterize the temporal development of the strength and deformation properties of the tested concretes to derive additional evaluation criteria for ASR performance tests.
