Abstract
An experimental method suitable for the determination of the
time-dependent tension softening response of early age concrete is
presented. The method is based on the wedge splitting test by
Tschegg, which is well known to be suited for
the determination of fracture mechanical parameters, i.e. the
fracture energy or the stress crack opening relationship as
defined in the fictitious crack model by Hillerborg. The setup is designed in a way that
eliminates self weight loading of the fracture process region and
allows for determination of the time-dependent crack mouth opening
displacement for a constant load applied to the setup. Possible
modelling strategies are outlined in the paper and preliminary
results are presented.
