The use of carbon nanotubes (CNTs) in concrete is gaining recognition for its ability to improve the strength and electrical conductivity and durability of the material. This extensive review thoroughly examines the ways in which CNTs impact concrete and including their effects on workability and mechanical performance and durability. When it comes to workability and CNTs generally reduce the ease of working with concrete. However and by adding dispersed liquid CNTs it is possible to enhance its fluidity. The review meticulously explores how CNTs affect properties such as compressive strength and split tensile strength and flexural strength in concrete reinforced with CNTs. The consistent findings show improvements in these aspects when using concentrations of CNTs. Additionally this review delves into durability considerations like resistance to chloride penetration and performance under temperatures and resistance to freeze thaw damage. It highlights that CNTs are highly effective in mitigating chloride penetration and reducing spalling under high temperature conditions while enhancing concrete’s ability to withstand freeze thaw cycles. Overall and CNTs have the potential as a building material that can enhance the quality of open doors for innovative applications in construction and infrastructure. This comprehensive exploration of CNT usage in concrete provides insights for researchers and industry professionals alike and with the aim of inspiring advancements and real world applications.
