BBR VT CONA CMM Two/Four monostrand post-tensioning system
The European assessed CONA® CMM Two and Four post-tensioning system is a monostrand system for internally unbonded applications. The standard tendons have 2 or 4 strand configurations. Typical applications include suspended slabs of any building structure, slabs on ground but also special applications such as water treatment plants and silos.
Key features
- Available in either 2 or 4 strand configurations
- Optimised for compacted strand – 15.2 mm diameter, 165 mm2 area, 1,820 MPa, Fpk = 300 kN
- Compact light-weight system ideal for suspended slabs and building applications
- Advanced proprietary monolithic anchorage for very small tendon centre spacings and concrete edge distances
- Application of full post-tensioning force at very low concrete strengths (fcm,0 = 20/24 MPa)
- High level of corrosion protection ensured with individual transition pipes and greased/waxed and HDPE sheathed monostrands
- Fixed couplers for joining tendons (CMM FOUR only)
- Restressable & exchangeable tendons perfectly suited for long-term inspection and maintenance
- European Technical Assessment and CE marking
