Field study of concrete maturity method in very cold weather.

摘要

The objective of this study was to assess the reliability and potential benefit of using the concrete maturity method in very cold weather. This report reviews the concrete maturity method, describes the technology, explains field observations, and discusses potential benefits of using concrete maturity method and technology in very cold climates.; The concrete maturity method is based on the idea that concrete strength development is strongly correlated with the curing temperature history. Findings from a case study in application of maturity method indicated significant potential reduction in project schedule. The study results indicated that the concrete maturity methodology enables better quality control through the accurate estimation of in-place concrete strength. In addition, the real time information available through the concrete maturity method allowed the project manager to be proactive in managing heating and protection to ensure that the proper level of concrete strength was developed.
