“…Due to the resulting novel cementitious composite containing additional bonding (healing) materials, it may be possible to exceed the initial, uncracked stiffness. This has already been proven by using the load‐CMOD (crack mouth open displacement) curve …”

When studying the self‐healing properties of construction materials, a plethora of destructive and nondestructive testing (NDT) techniques can be used. In this review, the applicability of different nondestructive test methods is discussed in detail. The methods can be categorized whether they are used to study the encapsulation and/or protection mechanism of the healing agent, the sequestered healing agent itself, the distribution of healing agents, the trigger mechanism for healing, the healing efficiency, or healing performance. Based on this categorization, nondestructive techniques found in literature are discussed. In this way, a robust understanding of the different techniques can be used for future research on self‐healing construction materials.

“…Microscopic analysis can be used to study one crack or multiple cracks. Not only wide cracks, but also narrow cracks can be investigated in great detail . Furthermore, by means of image analysis, the extent of healing, i.e., the visual closure of cracks, can be quantified.…”

Standard, steam and air curing methods were investigated in the scope of presented study to assess the healing performance of early age mortar damages. Compressive stress levels of 50, 75, 90 and 100 % of strength were adapted to Portland cement mortar or blended cement mortar specimens at early ages. Test results exhibited that preloading level under 90 % of instantaneous strength until 4 days, did not affect the ultimate strength for standard cured specimens. On the contrary, results obtained from air cured specimens preloaded after 2 days were almost equal or greater than that of control specimens. Surprisingly, steam curing application could not provide expected recuperation; however, less variable strength results were obtained. Blended cement mortar specimens achieved better results with steam curing process. Besides, it was possible to reach 53 MPa compressive strength by selecting a proper curing treatment even in the case of full damage. Erken Dönem Harç Hasarlarının

“…Hilloulin et al undertook a combined experimental/numerical investigation into natural healing of small cracks (5–20 µm) in cementitious specimens. In the numerical component of the work, the microstructural hydration model CEMHYD3D (or CEMPP) was combined with the finite element code Cast3M to simulate healing processes due to hydration.…”

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.
