“…However, the addition of nano-silica has been found to decrease concrete porosity, thereby reducing concrete deterioration. Two primary physical stressors, namely shrinkage and abrasion, can impair cementitious materials, leading to crack initiation and expansion throughout the cementitious material [ 70 ]. The performance of cement can be enhanced by incorporating nanoscale components into concrete.…”

“…The performance of cement can be enhanced by incorporating nanoscale components into concrete. Addition of nano-SiO2 to concrete containing high volumes of fly ash can significantly improve the compressive strength by filling the nanoscale gaps between large fly ash and cement particles, especially when the concrete is still fresh [ 70 ].…”

“…must be gathered, and an organic integration between the project and its natural setting must be sought. In other words, provide new design criteria and methodologies for civil engineering and integrate the idea of sustainable development into the early stages of the field [97]. These four elements make up the sum total of the criteria and approach used in civil engineering design:…”

In terms of the impact of human activity on the natural environment, civil engineering is one of the most significant productive pursuits. The production and use of building materials, the advancement of engineering and construction, the use of the project after it is completed, the removal of discarded components, and other procedures all require significant energy expenditure and ongoing waste generation, which can have severe consequences for the natural environment. To meet the demands of both economic and social development, advancements in civil engineering must be made while also protecting the natural world, limiting the use of natural resources, and promoting sustainable development. This study examines the long-term strategy in civil engineering and explores the role of environmental sustainability throughout the various stages of the civil design process, including the conceptual stage, the technical design stage, and the building stage. The research finds that the construction industry should adopt practices that adhere to sustainability principles such as environmentally-friendly design, durability, energy efficiency, waste reduction, improved indoor air quality, water conservation, and the use of sustainable building materials in construction.

“…A literature review indicates various options for improving the performance and changing the concrete parameters with the use of nanotechnology [10][11][12][13][14][15]. The most widely used and fully tested nanomaterials added into cement-based composites include nanosilica [16,17], nano-alumina [18], and nano-clay [19], which promote and accelerate the pozzolanic chemical reaction, imparting increased mechanical strength to the concrete.…”

Anatase, one of the polymorphs of titanium dioxide (TiO2), has become the most widely used semiconductor for photocatalytic materials due to its chemical and physical properties. However, researchers have been studying the use of alternative materials (e.g., ZnO, N-doped, and C-doped TiO2) to improve the photocatalytic activity of cementitious materials. In this paper, we propose a modification of lightweight concrete by introducing mixed phases of titanium dioxide—anatase and rutile—to enhance its photocatalytic performance. The efficiency of NOx degradation of nano TiO2-modified concrete, its self-cleaning performance, and its antimicrobial properties were studied. The photocatalytic activity of lightweight concrete without TiO2 and concrete with the addition of anatase, rutile, and anatase-rutile was compared. The results show that modifying the samples by adding a mixture of anatase and rutile (2.5 wt % A + 2.5 wt % R) significantly improved the photocatalytic performance of lightweight concrete.
