    Abstract
  • Concrete is a heterogeneous composite material composed of coarse aggregate, mortar and interfacial transition zone (ITZ). ITZ is the weakest phase inside the concrete and has a significant effect on the macroscopic fracture process of concrete. To respectively explore the effects of the distribution and value of ITZ strength on the crack propagation process in concrete under uniaxial compression, a discrete element model that reflects complex mesostructures of concrete aggregate, mortar and ITZ is established in PFC 2D by the use of FISH code. The numerical simulation results showed that cracks follow the propagation order from the centre of concrete to the loading end during the crack propagation process, and more than 80% of cracks appear in the softening stage after peak stress. The ITZ strength distribution has a weak effect on the crack propagation process in concrete, and the number of cracks in concrete is large when the ITZ strength shows a U shape distribution. The decrease in ITZ strength value leads to a gradual increase in the number and range of cracks. When the ratio of the minimum bond strength of ITZ to the bond strength of mortar p<0.5, the concrete strength is significantly reduced and the cracks expand around the centre of the concrete model to form a network macro-crack, resulting in scattered fracture failure. When p>0.6, the cracks expand from the centre of the concrete specimen to the loading end to form a macroscopic penetration crack, resulting in block fracture failure.
