Bond strength of hot – dip galvanized reinforcement (B500B) with concrete

Bond strength of hot – dip galvanized reinforcement (B500B) with concrete

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<sub>m</sub&...
