Abstract
This paper summarizes the application of nanomaterials in civil engineering structure repair and its challenges and optimization countermeasures. Firstly, the definition, classification and main characteristics of nanomaterials are introduced, which provides a theoretical basis for their application in civil engineering. Subsequently, three types of applications of nanomaterials in concrete restoration are discussed in detail: high-performance nano concrete, intelligent nano concrete and environmentally friendly nano concrete, which significantly improve the performance and sustainability of concrete. However, nanomaterials also face the challenges of unstable material performance, insufficient long-term performance evaluation, high material cost and complex construction technology. To meet these challenges, this paper proposes optimization countermeasures, including assessing the compatibility of different nanomaterials, establishment of environmental adaptive response mechanisms, development of low-cost preparation techniques, and dedicated construction techniques. These countermeasures aim to promote the wide application of nanomaterials in civil engineering structure restoration, improve the safety and durability of engineering, and promote the green and sustainable development in the field of civil engineering. This study provides theoretical support and technical guidance for the practical application of nanomaterials in civil engineering structure restoration.
