Monitor concrete strength in real time – wherever you are
The temperature of concrete during casting and curing has a direct impact on strength, cracking risk and service life. Too low a temperature can slow down strength development, while too high a temperature increases the risk of cracking and internal stresses.
By continuously measuring the concrete temperature, you get full control of the curing process in real time. This makes it possible to detect deviations at an early stage, adjust insulation or heat addition and ensure that the concrete achieves the right strength according to the project requirements. Remote monitoring of concrete also provides automated documentation – an important basis for quality assurance, control plans and follow-up in both small and large concrete projects.
The Celsicom remote monitoring system can be used to remotely monitor concrete temperatures during casting in real time. Thermocouple wires are embedded in a number of measuring points in the concrete and measurements are sent wirelessly to theCelsiview cloud service. Ambient air temperature is also recorded. In this way, it is possible to follow the initial temperature increase caused by the chemical reaction of the cement and the subsequent temperature decrease as the concrete hardens.
What is so revolutionary?
With the yellow Celsicom Easy Connect loggers, no base station is needed. Each logger has its own SIM card that transmits data directly to the cloud via the Telia Narrowband-IoT network. The result is better coverage and interference-free transmission of measurement data from temperature sensors in the concrete to the cloud service in your mobile.
The user can also choose which concrete recipe is used. A curve for the temperature dependence of the cement reaction and a strength curve are retrieved from a database. Customer-specific recipes can also be entered into the database. Using this input data, Celsiview can then show the strength of the concrete at the current ambient air temperature.
No special calculation programs are needed
In other words, the person in charge of casting can see how far the curing process has progressed and the strength of the concrete at each measurement point, without using special calculation programs. Just take your phone out of your pocket and log on to Celsiview.
What is needed to monitor the strength of concrete on a mobile phone?
In addition to the yellow concrete computer, what is needed to track the strength of the concrete is a cloud service account with optional strength calculation.
Two wire sensors can be connected to each Celsicom TC603. After logging in to the account and selecting the right concrete recipe in the cloud service, the strength curve is displayed directly on your mobile or computer.
The TC603 also has 1 built-in internal ambient temperature sensor.
Directly connected remote monitoring of concrete strength
The Celsicom TC603 concrete computer measures concrete and ambient temperatures. All data is sent to the cloud service, for full control of curing, wherever you are.
How does a strength measurement work?
Do this after connecting your sensors to your Celsiview account and selecting the concrete recipe (the service requires the Strength Calculation option):
1. Cast the wire sensors into the concrete, for example one in the center of the concrete slab and one at the edge near the mold.
2. Connect the other end of the wire sensors to the pole screws on the TC603 and close the cover.
3. clear! Now the values are continuously transferred to the cloud service and you will be able to follow the strength curve on your phone or computer, wherever you are.
What are the main advantages of being able to monitor concrete strength remotely?
Simplicity – no complicated calculation programs needed. With Celsicom, you can simply log on to the Celsiview cloud service via your mobile or computer and instantly see the strength of the concrete at different measurement points.
Remote monitoring – you don’t have to be on site. It is sufficient to have access to a computer or a mobile phone with an internet connection to view the graphs. In addition, several people in the project can easily access the measurement data.
Better construction time management – no more traveling back and forth if you are responsible for several sites at the same time where concrete is being poured.
Integration into your own tools – via Celsicom’s API it is possible to integrate measurement data into your own project tools.
Example of temperature and strength curve in Celsiview
Concrete computers facilitate casting of the West Link
At the Kallebäck exit west of the E6, concrete engineer Frida Mesch and her colleagues at NCC are busy casting in and outside the southern tunnel mouth of the rail link.
