Concrete Technology and Design of Concrete Structures Select the incorrect statement... For heavy loads and large spans in buildings or bridges, post-tensioning system is cheaper than pretensioning system The loss of prestress is more in pre-tensioning system than in post-tensioning system. Pretensioning system has greater certainty about its durability. None of these For heavy loads and large spans in buildings or bridges, post-tensioning system is cheaper than pretensioning system The loss of prestress is more in pre-tensioning system than in post-tensioning system.
