Sustainable and Smart Materials in Structural Engineering: Key Technologies for Future Buildings

Abstract

The construction industry faces mounting pressure to address critical environmental challenges, including resource depletion, energy inefficiency, and the substantial carbon footprint associated with traditional building materials. In response, the integration of sustainable and smart materials into structural engineering has emerged as a transformative strategy for creating resilient and environmentally responsible infrastructures. Innovative materials-such as bio-based composites, self-healing concrete, and energy-efficient smart systems-offer substantial benefits by reducing environmental impacts while enhancing overall building performance. Sustainable materials conserve natural resources, minimize waste, and lower carbon emissions, whereas smart materials adapt to environmental conditions, optimizing energy consumption and extending the lifespan of structures. This paper systematically examines key technologies and innovations in sustainable and smart materials that are reshaping structural engineering practices. By analyzing these advancements, it highlights their potential to revolutionize building design, reduce operational costs, and support the development of high-performance, eco-friendly structures. The study provides a comprehensive overview of these materials and technologies, underscoring their pivotal role in shaping the future of sustainable construction.
