Application of Smart Materials in Civil Engineering

Abstract

In the ever-evolving wave of technology, smart materials have emerged in the field of civil engineering, and their unique characteristics and wide application prospects have gradually become the focus of the industry. Not only do they sense and respond to environmental changes, but they also show great potential in critical applications such as structural health monitoring, seismic reinforcement, and self-healing, providing unprecedented solutions for the maintenance and construction of civil engineering. This article elaborates on the properties and classification of smart materials, and delves into their specific applications in civil engineering, covering structural health monitoring, seismic reinforcement, self-healing, and more. At the same time, the paper analyzes the challenges faced by the application of smart materials and looks forward to their future development trends. The conclusions of the study show that smart materials are revolutionizing many fields such as architecture, improving efficiency and stimulating new applications. In civil engineering, they enhance structural safety, maintenance efficiency, and environmental adaptation, such as self-healing concrete to extend life, smart sensors to monitor health, smart road systems to recover energy, and promote green buildings. Despite the challenges of cost and technology maturity, multidisciplinary integration, standardization and sustainable development strategies bode well for the industry to become smarter, greener and more innovative.
