Key features of CONA CMM:
- Compact light-weight anchorages available in two sizes which are optimized for either 12.9 mm or 15.7 mm diameter, 1,860 MPa strand
- CMM S2 anchorages are available in a variant without reinforcing the pressure zone.
- Application of full post-tensioning force at very low concrete strengths
- Minor distances between respective anchorages and edge distances
- Monolithic coupling anchorage with an integrated, preinstalled wedge (CONA CMM Single S2 system)
- Superior corrosion protection ensured with the use of monostrands and PE casings within the transition zone by the anchorage
- Fixed couplers available
- Possible implementation as a system of single strand bonded tendons (CONA CMM Single)
- Anchorages with possibilities of restressing and replacement
- European Technical Assessment and CE marking
