X-ray CT characterization and fracture simulation of ASR damage of glass particles in alkaline solution and mortar

•Monitor alkali silica reaction (ASR) damage inside glass aggregates with dynamic μm X-ray CT tests.•Apply discontinuous displacement method and boundary element method for fracture propagation simulation.•Update FRIC 2D codes with plane stress conditions and calibrated SIFs calculation.•Favorably c...
