CHALLENGES
For the precast company Contiga monitoring the temperature, strength and maturity development of each precast concrete element has been a manual and time-consuming task before using Maturix: All data had to be entered, read and processed manually and the insights were only available after the calculation was finished. Particular pre-tensioned concrete elements are a challenge in a precast factory: If an element has not reached the required strength and is processed, wire slippage occurs and the element is ruined. If the element cures for too long, unnecessary waiting time reduces efficiency.
- Follow the curing process for each precast element
- High risk of wire slippage with prestressed elements
- Boosting productivity while ensuring safety
SOLUTION
Using Maturix on a daily basis enables Contiga to get real-time insights into each precast element or bed. By integrating the Maturix sensors, a basis for the data-driven decision is enabled.
Using Maturix transmitters they measure and monitor the concrete temperature with all the surrounding influences and external effects.
In contrast to the traditional method of using data loggers and manual data collection together with several break tests, Contiga gets exact data from our sensors to always know the predicted strength of their concrete elements.
As they measure temperature with the cables directly inside the structure, they gain reliable data about the internal curing process in real-time which has not been possible before.
To ensure excellent coverage throughout the entire factory and all of Contiga’s production halls, one Sigfox gateway has been installed outdoor on their mixing tower. This allows the system to work anywhere in their plant, giving flexibility and ensuring connectivity.
The Maturix software provides Contiga with insights to improve their productivity while reducing the risk of slippage. Most importantly, the insights are based on facts. With real-time insight and knowledge about the curing process and strength development of the produced concrete elements, Contiga can act accordingly and proactively.
RESULTS
Contiga uses Maturix on a daily basis. Since they have started monitoring the strength development of their precast elements, they have reduced their risk of damage and the resulting waste from slippage drastically while increasing their capacity. Gaining insights into the curing process in real-time enabled them to optimize their concrete mix and reduce their break tests at the same time. The available dashboards and automatic documentation make Maturix further a valuable digitalization tool.
On average they have reduced the average production time for each element by more than 15%. For each monitored element, they cut down the curing time: the curing time of a hollow core element has been reduced on average from 10 hours to 7,9 hours and the curing time of a wall element has been shortened from 12 hours to 9,5 hours.
Further, waste due to slippage errors caused by insufficient curing are eliminated.
Based on the continous measurements, Contiga could further optimize their energy costs through the integration of their heating system.
- Optimization of concrete mix
- Increase of planning accuracy
- Optimization of the overall processes with increased productivity
- Elimination of waste due to slippage errors
