PT load transfer efficiency in extreme conditions

Recent cryogenic testing

The BBR R&D department has recently carried out the load transfer testing of CONA CMI in which the entire concrete testing block - including the bearing trumplate as the key load transfer element and the anchorage zone reinforcements - was completely subjected to cryogenic conditions. This test examined the load transfer efficiency of the system under these extreme conditions. The successful test results verify the performance of the BBR VT CONA CMI post-tensioning system and prove that it is still in full compliance with the ETAG 013 testing regime - even under cryogenic conditions.
