摘要：
The restoration of ultra high performance concrete (UHPC) specimens due to the self-healing phenomenon was investigated in this paper. A hydro-chemo-mechanical model based on micro-mechanical observations was established. The aim was to evaluate the mechanical properties of the new healing products in order to describe the partial recovery of the mechanical properties of healed concrete. An analysis of the influence of some physical parameters provided first explanations about the self-healing phenomenon. It was shown that the mechanical properties of CSH in the healed crack are lower than the ones of the virgin material. (C) 2014 Elsevier Ltd. All rights reserved.
