The Maturity Curve is a graph that represents the relationship between the maturity and the strength development. 

To find this relationship, you make some samples with the concrete mixture that you will use in your project and instrument some of them with temperature sensors. The samples are then cured under the same conditions and the temperature history is measured using the sensors. Then you need to perform break tests of the samples at different test ages to determine their compressive strength. With the strength data from the break tests and the maturity from the temperature history, Maturix® will plot the Maturity Curve.
