Özet

The bond between concrete and reinforcement is the most important property on emerging reinforced concrete. By means of this property, concrete and reinforcement resist together against the load applied to the reinforced concrete structural members and act to complement each other. It is known that, when exposed to elevated temperatures as a result of fire, load carrying capacity and resistance to the external effects of structural members decrease. In this reduction, it is important to know the proportion of the bond between concrete and reinforcement and the effect of temperature difference to the bond strength.
