Experimental behavior of concrete beams with externally bonded carbon fiber tow sheets
- West Virginia Univ., Morgantown, WV (United States)
The durability of structural materials is affected by the presence of air borne pollutants in combination with humidity and temperature variations that is harsh environment. Hence strength and stiffness degradation phenomenon in the bonded concrete beams exposed to harsh environment must be understood properly. The effects of weathering or aging of materials are being studied in the Major Units laboratory using an environmental chamber. In this research, effects of acidic and alkaline conditions and humidity at constant and varying temperature on the durability of steel reinforced concrete beams externally bonded with Carbon Fiber Reinforced Plastic Tow Sheet are studied. A total of thirty-six beams are tested after conditioning for accelerated aging to failure under static loads. Two wrapped and unwrapped control beams are tested under static loads. In addition to the above said beams, concrete cylinders and bond strength specimens were subjected to environmental conditions.
