Temperature is an important indicator to evaluate the concrete after it has been build. Traditionally, the concrete temperature is monitored by embedded sensors, but placing these is not convenient during pouring and the sensors can fail. A calculational method that does not need embedded sensors was developed where the concrete temperature field is determined from measured cooling flow temperatures. The mathematical model, instrument layout and monitoring procedure are described in this paper. Predicted temperatures for a domestic large arch dam project compare well with actual measurements to validate the applicability of the method.
