As people' s requirements for building quality are getting higher and higher, the use of building materials in civil engineering construction should also meet the modern environmental protection requirements. Therefore, it is proposed that the innovation and application of green building materials in civil engineering construction and analysis of green The characteristics of building materials, the innovative application of green building materials in engineering construction based on the characteristics, the use of green materials in building structures, the innovative application of exterior decoration, and the innovative application of interior decoration. Realize the application of green building materials in civil engineering construction.
