To determine which preconditioning and pretensioning techniques should be applied to soft tissue grafts during anterior cruciate ligament (ACL) reconstruction to avoid loss of tension after surgery, fresh semitendinosus and tibialis anterior tendons underwent tensile mechanical testing with 4 pretensioning and/or preconditioning techniques. A mechanical tester was used to collect the data. Grou...

This article expounds on the problem of use de-icing salts in corrosion steel rebars bridge decks and their effect post-tensioning elements. In particular, this paper focuses structures affected by an aggregate–alkali reaction without any waterproof treatment using example one structure whose repair was carried out 2020. structure, internal stresses due to caused longitudinal cracks upper face ...

This paper proposes a construction technology for the precision control of pedestal table and overall tensioning method composite beam steel strand Given because critical technical issues, such as deformation cracking during prestressed production process, group tensioning, bar slippage. Reinforcement fixing device research development node reinforcement arrangement its technologies based on BI...

In this preliminary study, the complexity of the corrosion phenomenon of post-tensioning strands in grouted anchorage assemblies was examined and both physicochemical and electrochemical key technical issues were identified. Measurements of oxygen reduction efficiency in high pH electrolytes were conducted to obtain polarization parameters to be used in modeling. The time evolution of electrica...
