(TU Delft Materials and Environment) Schlangen, E. (TU Delft Materials and Environment) van Breugel, K. (TU Delft Materials and Environment) Contributor Schlangen, Erik (editor) de Schutter, Geert (editor) Šavija, Branko (editor) Zhang, Hongzhi (editor) Romero Rodriguez, Claudia (editor) Date 2018 Abstract In order to gain a better understanding of the interaction between creep and micro-cracking during long-term creep process, a theoretical study was performed. An existing lattice model was modified to take creep into account. Based on the model, the micro-cracking in the creep process was simulated on a three-phase concrete sample under sustained compressive load (30% of compressive strength). The effect of on-going hydration and self-healing were considered in this process and inserted in the modified lattice model. This paper contains preliminary results of numerical simulations of an on-going study. The results show that continuous micro-cracking contributes to an extra deformation and degradation of mechanical properties, even though the on-going hydration is involved. The effect of self-healing in the damage zone leads to a decrease in the extra deformation and also to the recovery of the compressive strength and elastic modulus.
