Abstract

The paper discusses research progress on numerical models for self-healing cementitious materials (SHCMs). The paper considers models developed specifically for SHCMs, as well as other relevant work. This article provides a summary of current self-healing techniques along with descriptions of the processes that govern their behaviour. The paper discusses models for mechanical self-healing, transport processes in materials with embedded healing systems, fully coupled models and other modelling techniques used to simulate SH behaviour. The mechanics models discussed include those based on continuum-damage-healing mechanics (CDHM), micro-mechanics, as well as models that use discrete elements and particle methods. A considerable section is devoted to the simulation of carbonation in concrete since the essential mechanisms that govern this process are applicable to SH systems that employ calcite as a healing material. A number of transport models for simulating early-age self-healing are also considered. The paper highlights the fact that there are currently very few papers that describe fully-coupled models, although a number of approaches that couple some aspects of transport and mechanical healing behaviour are discussed. This article closes with a discussion that highlights the fact that many models have been presented with limited or no experimental validation.
