Abstract: The concrete infrastructure requires recovering the maximum information about the quality and state of the structural and constitutive materials. The evaluation of cement-based materials by non-destructive is still a necessary requirement. The use of embedded sensors and wireless sensor networks could be an attractive solution. This paper reports a study of the behaviour of concrete during the degradation process by freeze-thaw cycles. The temperature, humidity, and strain gauge sensors were embedded in concrete during its manufacturing to monitor the deformations produced in this process, while ultrasonic sensors were adhered to the outer parallel surfaces of the specimens after the curing process. The temperature, relative humidity, and ultrasonic signals were registered by wireless sensor networks. As a result, a diagnostic of the sample status during this process was obtained. Two specific mixtures were made and monitored to investigate the ordinary concrete mix proposed during the Cost Action TU1404.
