What is it about?
Comparison of the coating thickness and corrosion behaviour of both conventional hot-dipped galvanized and continuously galvanized reinforcing bars (rebar) in cracked and non-cracked concrete exposed to anti-icing agents (salts)

Why is it important?
The product of the new technology of galvanizing is the thinner coating on the continuously galvanized rebar that helps save cost and avoid cracks in coatings in the conventional hot-dipped galvanized rebar. How do both bars compare in their coating thicknesses around the bar and corrosion behaviour in cracked concrete exposed to salt like rhe bridge decks during winter seasons
Perspectives
Should we opt for the continuously galvanized rebar to reinforce concrete exposed to anti-icing brine? Be the judge
