“…The self‐healing efficiency of encapsulation‐based self‐healing concrete is primarily evaluated from initiation of self‐healing process by creation of cracks to assessment of self‐healing performances . The related test approaches are classified in Table , including initiation of self‐healing reaction, evaluation of self‐healing efficiency, and monitoring of healing process .…”

In this paper, research progress on numerical models for self‐healing cementitious materials (SHCMs) is discussed. Models developed specifically for SHCMs, as well as other relevant work, are considered. A summary of current self‐healing (SH) techniques is provided along with descriptions of the processes that govern their behavior. Models for mechanical self‐healing, transport processes in materials with embedded healing systems, fully coupled models, and other modeling techniques used to simulate SH behavior are discussed. The mechanics models discussed include those based on continuum–damage–healing mechanics (CDHM), micromechanics, 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. This 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 behavior are discussed. This article closes with a discussion that highlights the fact that many models are presented with limited or no experimental validation.

“…Commonly to all the other indices which will be hereafter reviewed, its values range between 0 (no-healing; wpost-healing = wpre-cracking) and 1 (complete healing; wpost-healing = 0). It is worth here remarking that this index will only account for the closure visible at the surface of the crack, whereas internal reconstruction of the through crack material continuity, which will govern as well the recovery of the material performance can only be assessed by means of methods such as X-ray or neutron radiography and tomography, microcomputer-tomography scan and electrical methods [2]. These methods, though employed in a number of healing related studies, have hardly led so far to any quantification of crack sealing through index such as in Equation (1).…”

“…The complexity of the scenarios described above requires a likewise comprehensive characterization of the healing mechanisms [2], and hence the last but not least "W" "WHY", which can rely upon methods ranging from classical ones, such as Electronic Scanning Electron Microscope (SEM-ESEM), as well Thermo-Gravimetry Analysis (TGA), X-ray Diffraction and Fourier Transform Infrared (FTIR) Spectroscopy to less common ones, which may go even down to the visualization of the healing products through X-ray microtomography [8] and the characterization of the signature properties of the healing products through nano-indentation [9,10].…”

“…Their implementation in the construction industry has been recognized as a pathway worth being travelled with the aim of improving the durability and long-term performance of structures made of and/or retrofitted with the aforementioned category of construction materials, able to extend their lifespan, also through the incorporation of new advanced functionalities to traditional materials. The variety of materials and techniques to either stimulate the autogenous healing capacity of concrete or engineer it [1], also through the incorporation of advanced functionalities, has been validated, in a much needed effort to assess their efficiency, through a multifold set of experimental tests and methodologies [2]. This paper will provide a synopsis on the topic.…”

This paper, prepared in the framework of the COST Action SARCOS WG2 activities (http://www.cost.eu/COST_Actions/ca/CA15202), provides an overview of the main concepts underlying the experimental characterization of the self-sealing capacity of cement-based materials. This effort intends to pave the way towards standardization of such experimental methods for a comparative assessment of the self-healing capacity of different cement-based materials and of the effectiveness of different techniques, in order to incorporate self-healing concepts and outcomes into durability-based predictive models and design approaches.
