Building materials can be divided into structural materials, decorative materials and some special materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, brick, ceramic, glass, engineering plastics, composite materials, etc.; decorative materials include various coatings, paints, coatings, veneers, various color tiles, special effects Glass, etc.; special materials are used for waterproof, moisture, corrosion, fire, flame retardant, sound insulation, heat insulation, heat preservation, sealing, etc. In the 1950s, China studied in the former Soviet Union at the former Tsinghua University, Nanjing Institute of Technology (now Southeast University), Tongji University, Chongqing Institute of Civil Engineering (now Chongqing University), Wuhan Institute of Building Materials (now Wuhan University of Technology) and other institutions of higher learning. Similar to the concrete materials, after the college entrance examination in 1977, except for Tsinghua University, other colleges and universities continue to enroll students. In recent years, with the expansion of enrollment and the demand for civil engineering materials, more than 20 colleges and universities nationwide began to Students enrolled in similar majors, compared to other majors, should be in short supply compared to such a broad civil engineering construction. However, the model that China's civil engineering design has followed for a long time, the design and construction are out of touch, the entire design, construction and use process are not attached to the material. The material engineer has always been a supporting role, and even many civil engineering design units have no special material talents. So the demand for these professions is not very large. But this has become history.
