Frost-damaged concrete: Part 2. Bond properties
Paper in proceedings, 2009

In an experimental investigation, pull-out tests were carried out on a reference and frost-damaged concrete. The level of frost damage was quantified by relative dynamic modulus of elasticity calculated from ultrasonic measurements. The test results showed significant influence of freeze-thaw cycles not only on the bond strength but also on the slip at the maximum bond. However, similar residual bond strength was observed for the reference and frost-damaged concrete. Finally, the results were compared with pull-out tests of frost-damaged concrete available in literature and the bond capacity and slip at maximum bond were discussed.
