Abstract
A method for predicting and controlling the strength development of concrete includes placing test concrete having the same composition as the subject concrete in a vessel which may be temperature regulated. The temperature inside the vessel is measured and recorded in a data memory and a data processor. The data is transmitted either in real time or from the data memory and data processor by way of a data transmission line to a temperature regulator for regulating the temperature inside the vessel. The temperature history of the test concrete can then simulate the temperature history of the reference concrete. The strength of the test concrete is measured at different times and the strength data of the test concrete is collected, processed and interpreted. A vessel for receiving the test concrete, a temperature regulator, a temperature controlling unit, a data recorder, a data transmitter and a computer are included.
