A mature technology is a technology that has been in use for long enough that most of its initial faults and inherent problems have been removed or reduced by further development. In some contexts, it may also refer to technology that has not seen widespread use, but whose scientific background is well understood. Its performance characteristics are also expected to be well .

Record URL. Maturity is a non-destructive approach to testing concrete that allows you to estimate the early-age and compressive strength of in-place concrete in real-time. Adopting the maturity approach in your jobsite eliminates the need for concrete cylinder break tests, allowing you to greatly optimize your schedule.

Pranab K. Mukherjee, Recent Developments in Accelerated Testing and Maturity of Concrete, TRB Cited by: The major limitations of the maturity method are: (1) the concrete must be maintained in a condition that permits cement hydration; (2) the method does not take into account the effects of early-age concrete temperature on the long-term strength (see Note 6) (3, 4); and (3) the method needs to be supplemented by other indications of the.
This page book presents the properties of concrete as needed in concrete construction, including strength and durability. testing, and new developments.
New chapters include information on. An alternative CO 2 curing method for precast concrete products has been proposed in order to achieve rapid strength development at early age, as well as to capture and store greenhouse gas (CO 2).In this paper, an experimental study for the development of a maturity approach is presented to estimate the strength development of carbonated concrete.
Transportation (WSDOT) to pursue and implement new technologies into the construction process to better serve the public. One of these new technologies is concrete maturity. Maturity is an approach to quality control that predicts the strength of the in-place concrete based on its internal temperature.
This book provides evidence and research to back these assertions.

Analyses of test results show that maturity can be used to predict compressive strength of concrete at early ages if the heat of hydration is duly incorporated into the evaluation of maturity. High-early-strength-concrete (HESC) made of Type III cement reaches approximately 50–70 % of its design compressive strength in a day in ambient conditions.
Experimental investigations were made in this study to observe the effects of temperature, curing time and concrete strength on the accelerated development of compressive strength in HESC. The maturity method can be used for determining adequate concrete strength in an element to allow release of the prestressing force.
A datum temperature of 50° F produced accurate predictions of the heat accelerated concrete. This value recommended as the default value for steam accelerated concrete items in cases where actual laboratory.
