The strength recorded from compression tests.
The time from concrete placement.
The strength within the first few hours or days after casting concrete.
The number of hours at a specified temperature required to produce a maturity equal to the maturity achieved by a curing period at temperatures different from the specified temperature. (1)
The required strength after 28 days.
The estimated strength of the field concrete.
The extent of the development of a property of a cementitious mixture. (1)
A curve presenting the strength-maturity relationship to be used for estimating the strength of the concrete mixture cured under other temperature conditions. (1)
A mathematical expression that uses the measured temperature history of a cementitious mixture during the curing period to calculate an index that is indicative of the maturity at the end of that period. (1)
An indicator of maturity that is calculated from the temperature history of the cementitious mixture by using a maturity function. (1)
Device that records the concrete temperature as a function of time and compute the maturity index.
A technique for estimating concrete strength that is based on the assumption that samples of a given concrete mixture attain equal strengths if they attain equal values of the maturity index. (1)
An empirical relationship between compressive strength and maturity index that is obtained by testing specimens whose temperature history up to the time of the test has been recorded. (1)
The required strength before demolding.
The time from concrete placement until compression test.
