Uniaxial Restraint Tests under High-Stress Conditions and a Chemo-Hygral Model for ASR Expansion
For evaluating damages of structural concrete by ASR, an analytical platform to rationally deal with the complex interaction of multi-scale chemo-physics events is being developed. For experimental verification of the predictive model proposed, ASR expansion tests under several magnitudes of confinement are conducted and the results are compared with the multi-scale simulation. It is experimentally found that the highly deviatoric compression may bring about isotropically confined ASR expansion. The poro-mechanics based multi-phase modeling can simulate this nonlinearity by considering the quasi-hydro static pressure of created ASR gels in concrete composites and its injection into the micro-pores.
