Select the incorrect statement...

Pretensioning system has greater certainty about its durability.

None of these

The loss of prestress is more in pre-tensioning system than in post-tensioning system.

For heavy loads and large spans in buildings or bridges, post-tensioning system is cheaper than pretensioning system
