Özet

The effects of elevated temperatures and cooling regimes on the residual (after cooling) bond strength between concrete and steel bars are investigated. For this study, ribbed steel bars of 8 mm diameter are embedded in to C20 and C35 concrete blocks with embedment lengths of 6, 10 and 12 cm. Unsealed specimens are heated to 12 different temperatures ranging between 50 and 700 degrees C and then cooled in water or in air. Pull-out tests are carried out on the specimens, and the effects of elevated temperatures on the residual bond strength are investigated by comparing the results against unheated specimens.
