Mechanical behavior of steel reinforcement before and after flame spray coating in marine environment

Corrosion of steel reinforcement is a major concern for durability of Reinforced Concrete (RC) infrastructure. In particular, corrosion of reinforcement raises important issues for reinforced concrete design and assessment, since it can impair not only the appearance of the structure, affecting the...
