 The 3D vascular to release healing materials at a specified crack  A pre-and post-healing study examined the microstructure of interior fissures  EDX analysis confirmed the consumption of Ca(OH) 2 and the generation of C-S-H  Mechanical properties and durability were restored within 28 days after damage Concrete's fracture susceptibility is due to its limited tensile strength, which can lead to cracks. Steel reinforcement is added to designated areas to address this issue, but minuscule cracks can allow liquids and vapors to infiltrate the reinforcing material, causing corrosion. Self-healing concrete can resist corrosion by mending and sealing minor cracks. This study aims to determine if fused deposition modeling (FDM) can fabricate innovative vascular networks and tubes from polylactic acid (PLA) created by using three-dimensional (3D) printing methods, and its characteristics were contrasted with those of two-and one-dimensional (2D) networks.The dimensions of the internal and exterior diameters were 4 and 5.6 mm, respectively. The researchers used a planetary ball mill to apply an organic polycarboxylate ether liquid and fly ash nanopowder to all vascular architectures. The prefabricated tubes were then incorporated into a concrete beam to enable self-repairing capabilities. The water-to-cement ratio was 0.6%; the mixture was 1 part cement, 2.16 parts water, and 2.98 other ingredients. The self-healing properties were assessed using a four-point bending test. The developed pipes can produce self-healing concrete by introducing nano fly ash particles and low-viscosity healing solutions into the blood vessel network, enabling the concrete to undergo self-repair mechanisms. The specimen that had 3D treatment restored its strength to 95% at flexural recovery.

“…The ability of artificial materials to self-heal any properties can increase their service life, reduce the cost of maintaining them in working condition and repairs, and also increase the level of safety of the structure or product as a whole. For this reason, SHMs are currently the subject of one of the most researched areas of materials science [4][5][6]. The advancement of self-healing effects finds its pinnacle in polymer materials, owing to their capacity to swiftly restore not only intermolecular bonds but also, under specific conditions, generate new ones during the cross-linking process.…”

“…The crack should have a maximum width of approximately 200 μm or smaller [6]. In autonomous healing, a notable illustration pertains to the controlled release of a stored healing agent through various types of capsules, such as polymer, glass, ceramic, and ZnO capsules [7][8][9][10][11]. Capsule-based self-healing offers limited healing agents, thereby mitigating the need for repetitive damage repair and the restoration of larger cracks [10].…”

The tensile zone of concrete is prone to cracking due to its limited ability to withstand tension. To address this issue, steel reinforcement is used in these specific regions. The occurrence of little cracks might potentially facilitate the ingress of liquids and gases into the reinforcing material, hence inducing corrosion. Self-healing concrete can repair and seal minuscule cracks, thus impeding the formation of corrosion. This study investigates the potential application of fused deposition modelling (FDM) for generating novel vascular networks and tubes using polylactic acid (PLA) as the material. Poly (lactic acid) (PLA) was fabricated using three-dimensional (3D) printing techniques, and its properties were compared to those of one-dimensional (1D) and two-dimensional (2D) networks. The external diameter measured 5.6 mm, while the internal diameter measured 4 mm. utilized a 10 ml volume to apply healing agents, specifically organic polyethylene glycol liquid and nano-powder (fly ash) derived from recycled materials, to all vascular structures (1D, 2D, and 3D). This application was carried out using a planetary ball mill. Following this, the prepared tubes were incorporated into a concrete beam to introduce self-healing capabilities. The water-to-cement ratio (W/C) utilized for all concrete mixtures was 0.6%, while the definite mixture proportions were 1:2.16:2.98. The quantification of the self-healing phenomenon was conducted by evaluating the restoration of load-carrying capacity following the application of a repaired specimen to a four-point bending test. Furthermore, these enhancements resulted in improved durability, increased compressive strength, and enhanced other physical characteristics. The pipes that are manufactured can be utilized to produce innovative concrete that possesses the ability to undergo self-healing processes, making it well-suited for various self-healing applications.
