3. Monitoring concrete maturity in the structure

3.1 Site preparation

If the maturometer planned for the site has a function for predicting the mechanical strength of concrete at young ages, it must also be able to capture a reference curve providing mechanical strength as a function of equivalent age, obtained experimentally (site calibration phase).

Prior to any maturometry operation, the user must have a concrete calibration file specifying the apparent activation coefficient of the concrete and the reference curve, as well as the anticipated positioning of the temperature probes and their protection on site. The device used must provide at least :

• changes in temperature as a function of age for each probe installed in the structure, and calculation of the...
