Enhancing Cold Weather Construction: Electric Curing Applications of Carbon Fiber Reinforced Concrete
摘要
Cold climates often pose challenges to the curing process of cementitious materials, leading to extended curing times, delayed construction schedules, introduced additional costs, and compromised structural integrity. To overcome this, the construction industry continually seeks innovative solutions to facilitate placing fresh concrete in adverse weather conditions. This study explores the application of electric curing of carbon fiber reinforced concrete (CFRC) as an alternative method enabling concreting in cold weather. A series of laboratory experiments are conducted to assess the impact of varying carbon fiber content on the mechanical properties of concrete. Additionally, an alternative electric current was applied to the developed CFRC, and its temperature increase due to Joule heating was monitored over time. The results indicate that a prototype system containing a temperature controller and a power supply can be used to maintain the temperature of fresh CFRC concrete within a predetermined temperature during cold weather. The development of CFRC for electric curing applications in cold weather not only addresses the challenges posed by adverse environmental conditions but also provides insights into the potential of incorporating advanced materials in construction practices.
