Study on thermal self-diagnostic and self-adaptive smart concrete structures
Smart structures are made by embedding sensors, actuators, and controllers into the structure during manufacture. Carbon fiber reinforced concrete (CFRC) can be used as both thermal sensor and thermal actuator because of the Seebeck effect and electrothermal effect, which have been reported. In this paper, two kinds of thermal smart concrete structure are designed using CFRC. First, the smart concrete beam embedded with four CFRC sensors is studied. Experimental results show that the smart concrete beam with CFRC sensors can monitor the process of the heat transfer and temperatures inside concrete. Then, embedding a CFRC sensor into a CFRC plate and connecting it to a controller result in a smart concrete system. Results show that it operates in situ, in-line temperature measurement and control with excellent stability.
