Modelling of autogenous healing in ultra high performance concrete [PDF]
Cement and Concrete Research, 2014 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 ...
