CONA CMF Flat Post-tensioning system

Now European approved

We are delighted to announce that the BBR VT CONA CMF BT Internal Post-tensioning System with Flat Anchorages has now obtained European Technical Approval ETA.
The new CONA CMF contains the latest post-tensioning technology for flat slabs requiring PT tendons with 02, 03 and 04 strands. The system is based on 0.5” (93 mm² and 100 mm²) and 0.6” (140 mm² and 150 mm²) standard bonded prestressing strand or monostrand (unbonded).
The new flat bearing trumplate has an optimal rectangular outer shape, which allows it to be installed in the thinnest slabs. Three different planes, whose slenderness has been designed to reduce the peak of the bursting stresses, transfer the load to the concrete and allow for full stressing at very low concrete strength.
The anchor head brings reliability and competitiveness to the system. The CONA CMF system has been tested against static load, fatigue load and load transfer to the structure. The system fully complies with the European Technical Approval Guideline ETAG 013.
