Application of Nanotechnology in Building Construction Using Carbon Nanotubes: A Review

The construction industry is a significant contributor to energy consumption and pollution. However, the integration of nanotechnology offers a promising solution to mitigate these issues. This review explores the potential of nanotechnology in building construction, focusing on the development of green building materials and energy-efficient structures. The incorporation of nanoparticles, such as Carbon Nanotubes (CNTs), can enhance the properties of building materials, including strength, durability, and workability. The CNTs possess excellent mechanical, electrical, thermal, and chemical properties, making them useful in a wide range of engineering applications. Although CNT composites have significant potential as reinforcing functional construction materials, further investigation and exploration are needed. The CNTs can also be used for repair mortars, self-healing concrete, and cracks recovery. Moreover, their use in building construction offers opportunities for energy savings and harvesting. However, assessing the sustainability and potential environmental and health risks associated with these materials is crucial. This review provides an overview of the properties, applications, and potential challenges of CNT in building construction, highlighting the need for further research on cleaner building nanomaterials. The findings of this review will contribute to the development of sustainable and energy-efficient building practices.
