Knowing the concrete´s temperature evolution makes possible to calculate the concrete maturity at every moment. The maturity method advantage is that, regardless of how concrete´s temperature evolves, a certain maturity value will be associated to a compression strength, as long as the mix dosage doesn't change neither the materials properties those compose the concrete.

This means that a maturity-strength calibration in concrete specimens is completely representative and it allows to determine the strength of a real element, regardless of the element temperature defer to the concrete specimen. Usually the concrete elements, as a massive element, experience a higher temperature and this make reach the target strength before than the concrete specimen.

The maturity method allows to estimate the concrete strength with a higher accuracy 

Also the advantage of measure directly the concrete elements instead of concrete specimens, that isn´t 100% representative, is that the maturity method allows detect changes in the raw material characteristics if the mix has not changed it dosage: a temperature variation in similar conditions can be caused by the cement lots variation, admix changes, etc. The maturity method add this dimension to the routinary quality control and allow investigate the variation origins, and also just in a couple hours term.
