Professor Lee Bang-yeon's team from the Department of Architecture at CNU has succeeded in developing fiber-reinforced concrete that not only reduces carbon dioxide emissions but also ensures economic feasibility.
 
The fiber-reinforced concrete developed by the research team exhibits more than 8% improved deformability while significantly reducing carbon dioxide emissions, inherent energy, and cost.
 
Fiber-reinforced concrete is a construction material developed to improve the low tensile strength and deformability of traditional concrete. However, it requires a large amount of cement, resulting in high carbon dioxide emissions and energy consumption. Moreover, the use of expensive synthetic fibers (priced at 30,000 to 60,000 KRW per kilogram) poses challenges for practical implementation due to low economic feasibility.
 
Professor Lee’s research team has made groundbreaking improvements by completely replacing cement and expensive synthetic fibers with cellulose, an industrial byproduct and waste material from the textile industry.
