BBR VT CONA CME external post-tensioning system
The European assessed CONA® CME post-tensioning system is the ultimate multi-strand technology for all types of externally post-tensioned applications. The standard tendon sizes range from 1 to 73 strands. CONA CME can be applied for the prestressing of bridges, precast segmental construction and repair and strengthening works of all kind of structures.
Key features
- Standard tendon sizes from 1 to 73 strands, larger sizes on request
- Widest range of tendon sizes with the largest tendon forces available on the international marketplace
- Optimised for 15.7 mm diameter, 1,860 MPa strand
- The most compact & light-weight system available utilizing an advanced proprietary load transfer element for very small tendon centre spacings and concrete edge distances at the anchorages
- Application of full post-tensioning force at very low concrete strengths (fcm,0 = 19/23 MPa)
- Fixed couplers for joining tendons
- Smooth round tendon duct utilizing either galvanized steel or HDPE material
- The ducts can be injected with either a high performance BBR grout or grease/wax. Greased and HDPE sheathed monostrands in grout filled ducts are also possible
- Restressable & exchangeable tendons perfectly suited for long-term inspection and maintenance
- Fully encapsulated and electrically isolated tendons offer the highest level of corrosion protection possible
- European Technical Assessment and CE marking
