The two-story building on the Dresden University of Technology campus in Germany became the world's first building made of carbon fiber reinforced concrete. The world's first building made of carbon fiber reinforced concrete, called Carbonhaus, was achieved through the joint efforts of engineers, designers and researchers. For many years, they have advocated the use of advanced materials to replace traditional concrete and steel in buildings. The project cost 5 million euros and was funded by the German Federal Ministry of Education and Research.
The 2,200-square-foot building consists of a prefabricated box and a double-curved roof, and uses lightweight and soft composite materials. The carbon fiber used in this project is produced from polyacrylonitrile (PAN). According to Barzin Mobasher, a professor at the College of Sustainable Engineering and Built Environment at Arizona State University, at least half of the concrete in typical building components is used to protect the steel bars from corrosion. Because steel and concrete are "worked in series, not working together," The resulting components continue to be prone to cracking and corrosion.
Manfred Curbach, director of the Institute of Concrete Architecture at Dresden University of Technology, is another industry veteran who advocates the use of advanced materials in construction. He said that composite components are more durable, It is more environmentally friendly and can save up to 70% of greenhouse gas emissions. Taking into account labor, equipment, manufacturing and transportation, the cost of carbon fiber reinforced concrete is equivalent to steel, the cost of both is 13-15 US dollars per kilogram.
Carbon fiber reinforced concrete (CFRC) is a composite material that integrates multiple functions and structural properties. It is mainly by adding a small amount of carbon fiber and ultrafine additives (dispersant, defoamer, early strength) to ordinary concrete. Agent, etc.) composition. Compared with ordinary concrete, it not only has better mechanical properties, but also has many excellent characteristics.
In the 1970s, the United Kingdom took the lead in processing PAN-based carbon fiber reinforced cement-based panels and applied them to construction, setting a precedent for CFRC research and application. CFRC has the advantages of wear resistance, shrinkage resistance, impermeability and chemical resistance, and is an ideal choice for coating of building materials and pavement materials.
