BBR VT CONA CMF flat anchorage post-tensioning system
The European assessed CONA® CMF post-tensioning system is a multi-strand technology for internally post-tensioned bonded or unbonded applications in ultra thin concrete cross-sections. Typical applications include car parks, apartment buildings, commercial office space, retail centers, distribution warehouses and bridge deck slabs.
Key features
- Anchorages available with configurations from 2 up to 6 strands
- Compact lightweight anchorages optimized for either 12.9 mm or 15.7 mm diameter, 1,860 MPa strand
- Application of full post-tensioning force at very low concrete strengths fcm,0 = 17/23MPa (CONA CMF S1)
- Advanced proprietary load transfer element for very small tendon center spacings, concrete edge distances and slab thickness’
- Fixed couplers for joining tendons
- Corrugated flat tendon duct utilizing either galvanized steel or plastic material
- For bonded applications the ducts are filled with high performance BBR grout
- For unbonded applications the ducts can be injected with grease/wax or circulating dry air
- Restressable & exchangeable tendons perfectly suited to long-term inspection and maintenance
- System is compatible with greased and HDPE sheathed monostrands
- European Technical Assessment and CE marking
