Date Apr. 28, 1983.A method and device for controlling the curing rate of concrete comprising the measuring of the temperature of the concrete, assessing the momentaneous maturity of the concrete by means of the temperature variation and controlling the heat supply or dissipation on the basis of the momentaneous maturity in a manner such that at the end of the period the concrete has the desired maturity. A preferred embodiment of the device according to the invention comprises a temperature measuring device (15) to be connected to at least one temperature sensor (6,7), and a calculating device (16) connected to the temperature measuring device (15), assessing the momentaneous maturity and provided with a data input member (17) and a display member showing the assessed momentaneous maturity. |
