Remaining Bond Strength of Adhesive Post-Installed Rebar of Injection Type After Fire
Abstract eng: The experiments of post-installed adhesive anchoring systems of three kinds of injection, epoxy, urethane and in-organic were taken in focusing on bond failure (bond strength) after fire assumed joints between members in long term. The following conclusions were recognized by their experiments. First remaining bond strengths after fire have different performance depends on kinds of adhesion. Second remaining bond strength of epoxy injection resin type have the same performance of normal temperature in short term up to 275 ℃ after fire and cooling down to air temperature. Third remaining bond strengths after fire decrease in accordance with increase of heated temperature and are approximated by linear straight lines. Forth it is supposed that a test method for evaluating remaining bond strengths after fire assumed joints between members in long term.
