Sumario:In this paper a system is presented to monitor in-situ the curing process of sprayed concrete. This system consists of an instrumented trough based on wireless sensor networks for monitoring temperature/relative humidity and ultrasounds. The trough has been designed using a trapezoidal cast with several encapsulated transducers and an electronic system for generation, acquisition and processing of ultrasonic signals. A methodology for the measurement of ultrasonic velocity has also been proposed. This system has been proven to be a very good solution for in-situ monitoring of the curing process of sprayed concrete, being able to detect problems or defects in the material fabrication.
