In recent years, with the continuous development of the technical level in the field of construction, new civil engineering materials have a wide range of applications in various fields, the limitations of traditional building materials lead to the need for more sustainable and cost-effective alternative materials to meet the construction needs of civil engineering. This paper analyzes the new civil engineering materials, discusses the characteristics of high-performance concrete, new steel and composite materials, and analyzes the application strategies of new civil engineering materials in practical application fields, aiming to provide constructive suggestions for improving the construction quality of civil engineering and the application efficiency of new materials.
