Abstract
Estimating the compressive strength of concrete at an early age is critical for quality control and management of concrete construction. Although previous studies have made significant efforts to automate this process, they all have shortcomings regarding the long transmission range needed for a typical construction site and the corresponding power consumption. The present study uses a long-range wide-area network (LoRaWAN) system, a relatively new wireless sensor network technology, to overcome these limitations. In addition to the long transmission range, the features like low power consumption and cloud connectivity available with the system are essentially required for large construction sites. An energy harvesting unit is integrated with the proposed system to make it environment-friendly by reducing the carbon footprint significantly. The efficacy of the proposed system is demonstrated for real-time monitoring of early-age concrete compressive strength using the maturity method through laboratory and field experiments considering a typical concrete mix.

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
