With the continuous development and progress of domestic economic level and scientific and technological level, the construction technology level in the construction industry has also been significantly improved. In order to meet the national requirements for energy conservation and environmental protection, the new building materials with good energy conservation and environmental protection performance have been more and more used in construction projects. The application of various new building materials will not only reduce the pollution and damage of the project construction to the surrounding environment, but also further improve the construction quality of the project, and promote the continuous development of the civil engineering industry. Based on this, the paper studies the application of new building materials in civil engineering construction, in order to promote the development of the construction industry, for its reference.
