Abstract
Abstract The overall objective of this study is to investigate the effect of the fire flame and air post-fire curing method on the bond, compressive strengths and elastic modulus of self compacted concrete specimens for different curing durations. A total of forty-five specimens were cast and tested under compression and pullout tests. The specimens of the SCC were exposed to fire with temperature 600 °C and then cooled in the air to room temperature. In order to fully understand the effect of the air post-fire curing method on concrete strength, both tests were carried out after post-fire cured in different durations 7, 30, and 60 days. The test results demonstrated that air curing results show a significant resistance recovery and its extent depends on the period of air curing. The main contribution of this work is to prove that air post-fire curing can enhance the elastic modulus and the bond strength between steel bar and concrete.
