Concrete maturity testing is a solution for the construction industry to help assess the compressive strength of the concrete as described in ASTM C1074. The testing can aid in decisions regarding concrete curing conditions and mix design.
Maturity testing is specifically defined as the relationship between concrete temperature, time and strength gain and represented by an index that can be measured in the field in realtime.
The maturity method of concrete testing usually does not require as much field-testing of specimens like beams and cylinders, which do not necessarily show the actual pavement strength. Another big advantage of maturity testing is that it can allow pavement to be opened to traffic quickly and for fast-trackprojects.

Humboldt Maturity Meters provide a predictable strength determination of cast-in-place concrete based on ASTM standard C1074-98 (Estimating concrete strength by the maturity meter method). These units utilize inexpensive, disposable, T-type thermocouple wire with quick-connect jacks, which can be embedded directly into a concrete structure to measure temperature at timed intervals. These readings can then be used to document the maturity process within the structure in order to:
