Bagheri-Zadeh, S H; Kim, H; Hounsell, S; Wood, C R; Soleymani, H and King, M (2007) Field study of concrete maturity methodology in cold weather. Journal of Construction Engineering and Management, 133(11), pp. 827-835. ISSN 0733-9364
Abstract
The objective of this study was to assess the reliability and potential benefits of using the concrete maturity method in cold weather. This paper reviews the concrete maturity method, describes the technology and field observations, and discusses potential benefits of using concrete maturity in cold climates. The concrete maturity method is based on the idea that concrete strength development is strongly correlated with the curing temperature history. Modern sensor and processing devices (loggers) are able to measure and record the temperature of concrete over time. This information could be used to predict concrete strength over time. Findings from a case study in application of the maturity method in an industrial construction project in Edmonton, Alta., Canada indicated a significant potential time and cost reduction. The study also indicated that the concrete maturity methodology enables reliable quality control through the accurate estimation of in-place concrete strength. 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.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
