英文摘要We present a new model for fast and efficient simulation of long-term concrete degradation due to alkali silica reaction (ASR) and carbonation. The novel model provides an alternative coupling solution of reactive transport and multiphase multi-component flow by approximating the complex chemical reactions into a quickly calculating look-up table, which can further be integrated into a two-phase multi component transport model via source/sink terms. The complex dynamic interplay between chemistry and multi-phase transport are well addressed in this approach. A 1-D reactive transport benchmark is proposed by taking into account the two main chemical reactions which drive the concrete degradation: ASR and carbonation caused by transport of CO2 in a gas phase. We contrast three different sets of simulations to explore the pattern of competition between ASR and carbonation in the long-term degradation of concrete. The numerical model derived from the look-up table approach is compared to a full reactive transport code to validate its accuracy and efficiency. It is shown that the look-up table approach and the full reactive transport code produce very similar results for degradation of concrete even for the case of competition between ASR and carbonation. However, in terms of performance, it is observed that the look-up table approach leads to a considerable reduction in calculation time. Future work will be focused on incorporating the proposed model with a geo-mechanical model for multi-chemo-physics analysis of the concrete evolution. (C) 2018 Elsevier Ltd. All rights reserved.
