Ensuring the required quality of steel fibre reinforced concrete is of great importance. In particular, a homogeneous fibre distribution in the concrete is crucial. The DAfStb-Guideline on SFRC provides sufficient methods for quality control, however these are noticeably labour-intensive. The assessment of those test methods is limited and real-time test results are difficult to provide. For common applications there is sufficient experience to enable adequate quality control with the use of existing codes and guidelines.

However, quality control can now be executed even more precisely:
For particularly high requirements, or simply to carry out more comprehensive homogeneity measurements beyond the requirements of the regulations, we have the opportunity to access the eyeD® device developed by NV Bekaert SA, and to use it on the construction site.

An automated real time quality control system is an ideal solution, both in terms of process integration as well as quality assurance. The eyeD® is connected to the truck mixer by an adjustable interface and should fit all major truck mixer types. The concrete flow is continuously determined through regular ultrasound height sensors and especially developed speed sensors. The variation of the fibre’s electromagnetic response is measured and plotted as a deviation from the mean value. Results can be accessed as soon as the concrete discharge process has finished.

This can be done with any WiFi- capable device right on site. The eyeD® provides instantaneous quality data in real time. Corrective actions can be taken immediately if deemed necessary.
