For the creation of healable cement concrete matrix, microbial self-healing solutions are significantly more creative and potentially successful. The current study investigates whether gram-positive “Bacillus subtilis” (B. subtilis) microorganisms can effectively repair structural and non-structural cracks caused at the nano- and microscale. By creating an effective immobilization strategy in a coherent manner, the primary challenge regarding the viability of such microbes in a concrete mixture atmosphere has been successfully fulfilled. The iron oxide nanoparticles were synthesized. The examined immobilizing medium was the iron oxide nanoparticles, confirmed using different techniques (XRD, SEM, EDX, TGA, and FTIR). By measuring the average compressive strength of the samples (ASTM C109) and evaluating healing, the impact of triggered B. subtilis bacteria immobilized on iron oxide nanoparticles was examined. The compressive strength recovery of cracked samples following a therapeutic interval of 28 days served as a mechanical indicator of the healing process. In order to accurately correlate the recovery performance as a measure of crack healing duration, the pre-cracking load was set at 80% of the ultimate compressive stress, or “f c,” and the period of crack healing was maintained at 28 days. According to the findings, B. subtilis bacteria greatly enhanced the compressive strength and speed up the healing process in cracked cement concrete mixture. The iron oxide nanoparticles were proven to be the best immobilizer for keeping B. subtilis germs alive until the formation of fractures. The bacterial activity-driven calcite deposition in the generated nano-/micro-cracks was supported by micrographic and chemical investigations (XRD, FTIR, SEM, and EDX).

“…In addition to concentrating on nanomaterials in green architecture, this research demonstrated the significant effects that realworld technological applications in green architecture have on the macroeconomic situation of the nation and the economic well-being of families through statistical calculations and tests. The use of NPs in green architecture has been advocated by researchers as a way to reduce energy loss in industrial and residential buildings and to plan for power production and consumption at the national level [37]. The application of nanotechnology in architecture represents the trend in technology toward improved built environments on a global scale.…”

The field of nanotechnology has revolutionized the architectural sector, particularly in the domain of preserving cultural heritage. The gradual deterioration and degradation of ancient and heritage buildings pose significant challenges for the conservation of our cultural legacy. This review aims to emphasize the crucial role of nanotechnology in extending the lifespan of archaeological materials and artefacts, which are essential components of our cultural heritage. Archaeology encompasses both theoretical and applied methods, with applied archaeology involving activities such as excavation, restoration, and monument conservation. These practices heavily rely on the integration of novel findings from various disciplines including physics, chemistry, and geology. Nanotechnology has emerged as a promising approach within the realm of applied archaeology, offering innovative solutions for the preservation of organic and inorganic archaeological materials. This research focuses specifically on the applications of nanotechnology in conserving and restoring inorganic archaeological materials, particularly stone artefacts and buildings constructed from materials such as limestone or sandstone. By exploring the potential benefits and highlighting the significance of nanotechnology, this study seeks to underscore its role in safeguarding our cultural heritage and promoting sustainable construction practices.
