Abstract

The paper summarises the aspects of testing and influencing of reinforcement-concrete bond strength. It is focusing on the assessment of the extent of influence of the inevitable corrosion of the zinc coat in fresh concrete. The impact on concrete bond strength induced by evolving hydrogen and expanding zinc corrosion products is verified on plain steel bars. The zinc coat was produced by a conventional hot-dip galvanising technology. Standardised prism tests according to ČSN 73 1328 (“pull-out test”) were applied to test reinforcement-concrete concrete bond strength. The conclusion discusses also other impacts that might affect the cohesion progress, namely the impact of the contents of chromium (VI) compounds in the used concrete and the composition of the deposited coat.
