Hi guys,

When does post-installed rebar with a high bond strength perform better than a cast-in rebar?

Hello community members,

In general, the post-installed rebar has a higher bond strength capacity than the cast-in bar due to the load being transferred through the adhesive using micro-interlocking with the surface of the concrete. This layer allows the stresses to be more uniformly distributed and results in a more favourable performance. In the case of the cast-in bar, the loads are transferred via mechanical interlocking with the ribs and this provides more concentrated stresses perpendicular to the loading direction. 



Cheers!
