Temperature Sensitive Properties of Hybrid Carbon Nanotube/Carbon Fiber Cement-Based Materials

Abstract:

This paper gives an assessment on the temperature sensitive properties of hybrid carbon nanotube/carbon fiber cement-based materials. Different dosage of carbon nanotube (CNT) were added into a carbon fiber (CF) cement system to produce carbon nanotube-carbon fiber cement nanocomposites in the form of pastes. The temperature sensitivity coefficient, activation energy during heating and cooling, repeatability, linearity and electrical resistivity are tested. Results show that a high dosage of CNTs into cement paste can increase the temperature sensitivity coefficient, activation energy, repeatability and linearity, which has a vast potential for future development of temperature monitoring in concrete structures.
