Sažetak

This paper evaluates the effect of initial corrosion damage to the surface of the hot - dip galvanized steel coating in fresh concrete on its final bond strength. The tests were performed on uncoated and hot-dip galvanized ribbed reinforcements. The measurement of bond stress (τ_m) according to the standard procedure (ASTM C234; ČSN 73 1328) revealed decreased bond strength of the coated reinforcement. Both types of reinforcement exhibit similar values of maximum shear stress (τ). To make some general conclusion, the bond strength also needs to be verified on smooth profiles.
