BBR VT CONA CMI internal post-tensioning system
The European assessed CONA® CMI internal bonded or unbonded post-tensioning system is internationally the most up-to-date and advanced multi-strand PT technology, ranging from 1 to 73 strands. It is typically used for bridges (both cast in-situ and precast), LNG/LPG storage, tanks & silos, nuclear power plants and stadiums.

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 15.7mm 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 and movable couplers for joining tendons
- Corrugated or smooth round tendon duct utilizing either galvanized steel or plastic material
- For bonded applications the ducts are filled with BBR grout
- For unbonded applications the ducts can be injected with grease/wax or circulating dry air. Greased and HDPE sheathed monostrands in grout filled ducts are also possible
- Superior cryogenic performance ideal for LNG tank applications
- 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
