UK, 5 october, 2016.- The procedure for estimating the in-place strength requires measuring the in-place maturity. This is achieved by installing sensors at locations in the structure that are critical in terms of exposure conditions and structural requirements. The importance of this step cannot be over emphasised when the strength estimates are being used for the timing the start of critical construction operations.
Doka’s Concremote product and data driven service conforms to all of these International Standards and the Concremote sensors measure simultaneously the in-place concrete and ambient temperatures and time and compares this real-time data against a known calibrated concrete mix results and raises real time alerts when the required in-place target concrete strength is reached. Facilitating the optimization of on-site production activities. Typical data feeds from the Concremote monitoring service are:
The four fold tangible benefits of using the Concrete Maturity method are:
The contractor can build faster, safer, to better quality and at the same time provide real environmental benefits. All these benefits are simultaneously achieved through the deployment of Doka’s Concremote concrete real time measuring, monitoring and alert service.
Doka’s Concremote service utilises GSM and web based technologies to provide
Construction sites and Construction managers with continuous real time data and to take away the time and effort when using standard cubes or cylinder to provide incremental strength readings.
This analysis provides an introduction to the maturity method for establishing in-place strength development of concrete during construction. The proper application of this simple procedure can result in savings by allowing construction operations to be performed safely at the earliest possible time.
The Maturity Method also allows for the assessment of other concrete properties and the real time thermal monitoring of the hydrating concrete at various critical points within the pour to mitigate the risk in the development of thermal cracks. And, also when there is the need for producing architectural concrete finishes where a consistent colour tone is specified. But more about these in a later Doka whitepaper.
