Nanomaterials have become a revolutionary power in structural engineering, bringing unprecedented improvements in construction materials' mechanical, chemical, and thermal properties. The advanced materials work at the nanoscale, thus showing more strength, durability, and environmental adaptability than could be achieved by traditional materials. This paper discusses the various types of nanomaterials, such as silica nanoparticles, carbon nanotubes (CNTS), graphene, and Nano clays, and analyses their specific roles and benefits in construction applications. Critical thrust areas are nano-silica for higher performance of concrete, graphene for lightweight but robust composites, and nanocoating for high corrosion resistance. In terms of structural benefits, sustainability is also achieved through increased material efficiency and extended usage of infrastructure. Lifecycle assessment, however, indicates that improved emissions are realised through optimised functionality where nano-enhanced materials bring value, but challenges remain for their widespread adoption. Problems include high production costs associated with energy-intensive manufacturing and some apprehensions regarding ecotoxicity. It covers the economic feasibility of nanomaterials. It proves how the long-term benefits are realised through cost savings in terms of maintenance and repairs while investing in nanomaterials. A comparison between lifecycle costs and emissions would elucidate these benefits. It indicates the research gaps to be covered for the implementation of nanotechnology in structural engineering, which include toxicity testing, recycling techniques, and standardised integration protocols. Scaling up nanomaterial production techniques can be a focus area for future research, thereby making nanomaterials more accessible and cost-effective. Collaboration between the private sector, policymakers, and researchers is important for navigating current challenges and making the most of nanotechnology to implement sustainable infrastructure development. In that sense, this discussion bridges the gap between pure innovative inquiry and practical implementation.
