Abstract
The estimation of the early age compressive strength of concrete is crucial for quality control in the construction industry. The present study proposes an innovative and cost-effective Internet of Things (IoT)-enabled system for the real-time monitoring of early age concrete strength. The proposed system consists of temperature sensors and Wi-Fi microcontrollers that are connected to a cloud-based platform. Five selected concrete mixes are used to demonstrate the proposed system. The maturity relationships for the selected mixes are developed in the laboratory as per the relevant standards. The early age compressive strengths of the selected concrete mixes are predicted using the established maturity relationship, and the results are found to match well with the actual compressive strengths. The proposed system is found to be effective in the automation of the maturity method that can trigger the implementation of user-friendly Internet/mobile applications for the monitoring of the early age compressive strength of concrete required in the construction industry.

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
