“…• Advanced engineered cementitious composite. In recent years, significant numbers of smart, green, and innovative materials or techniques, such as hollow glass microspheres (Aslani et al, 2021), ceramic polishing brick powder (Xiong et al, 2021), microbially induced calcium carbonate precipitation using Aerobic nonureolytic bacteria (Justo-Reinoso et al, 2021) have been utilized into ECC to enhance the material sustainability in the construction industry. However, studies on the effects of these materials on the strength and durability performances of the ECC subjected to elevated temperature are very new research and need to be conducted.…”

This paper discusses the quantitative bibliographic data derived from scientific publications on Engineered Cementitious Composites (ECC) subjected to elevated temperature, the influence of elevated temperature on the mechanical properties, particularly the compressive strength and microstructure behavior of Engineered Cementitious Composites (ECC) mixtures based on the review of previous pieces of literature. Systematic literature reviews were employed as the methodology in this study. The age of related publications selected to be reviewed was limited to publications for the past ten years, 2010 to December 2020. It was found from available research that exposure of the ECC specimen at the elevated temperature starting from 200oC significantly reduced the compressive strength when the temperature increases, melting of fiber and increase of porosity causes the dramatically increase micro-cracks.

“…Self-healing of cement-based materials is not an entirely new problem. In 1836, self-healing in water-retaining structures was reported by the French Academy of Sciences; the hydration of cement-paste-like calcium carbonate or polyacrylic hydrogel was utilized for repairing cracks in cementitious materials [34][35][36][37][38]. This approach has now been extended to treating cracks with a size from a few microns to the millimeter scale, thus achieving a more practical use in real structures.…”

Self-healing materials have been developed since the 1990s and are currently used in various applications. Their performance in extreme environments and their mechanical properties have become a topic of research interest. Herein, we discuss cutting-edge self-healing technologies for hard materials and their expected healing processes. The progress that has been made, including advances in and applications of novel self-healing fiber-reinforced plastic composites, concrete, and metal materials is summarized. This perspective focuses on research at the frontier of self-healing structural materials.

“…The ability of a large community of bacteria to transform a suitable nutrient source into insoluble calcite crystallites-known as microbially induced calcium carbonate precipitation (MICP)-has been used as a part of biotechnologies representing an alternative to traditionally applied methods. Among others, MICP is exploited in dentistry [1], soil bioconsolidation [2][3][4], grouting technologies [5,6], water remediation [7,8], conservation of stone artworks [9,10], and, in particular, civil engineering [11][12][13][14][15]. The formation of calcium carbonate (CaCO 3 ) requires the presence of sufficiently high concentrations of calcium cations (Ca 2+ ) and carbonate anions with a saturation level greater > 1 [16].…”

Self-Healing of Cementitious Materials via Bacteria: A Theoretical Study

Cracks on the surface of cementitious composites represent an entrance gate for harmful substances—particularly water—to devastate the bulk of material, which results in lower durability. Autogenous crack-sealing is a significantly limited mechanism due to a combination of the hydration process and calcite nucleation, and self-healing cementitious composites are a research area that require a great deal of scientific effort. In contrast to time-consuming experiments (e.g., only the preparation of an applicable bare concrete sample itself requires more than 28 days), appropriately selected mathematical models may assist in the deeper understanding of self-healing processes via bacteria. This paper presents theoretically oriented research dealing with the application of specific bacteria (B. pseudofirmus) capable of transforming available nutrients into calcite, allowing for the cracks on the surfaces of cementitious materials to be repaired. One of the principal objectives of this study is to analyze the sensitivity of the bacterial growth curves to the system parameters within the context of the logistic model in the Monod approach. Analytically calculated growth curves for various parameters (initial inoculation concentration, initial nutrition content, and metabolic activity of bacteria) are compared with experimental data. The proposed methodology may also be applied to analyze the growth of microorganisms of nonbacterial origin (e.g., molds, yeasts).
