This paper deals with erosion-corrosion of steel in contact with flowing fresh concrete. Results of tests performed in fresh mortar on rotating cylindrical and disk electrodes are reported. The fresh mortar was manufactured by using chemical admixtures in order to retain constant workability during long time tests. Electrochemical and weight loss tests were conducted. SEM analysis was carried out to evaluate damage morphology. Damage mechanisms and corrosion behavior are discussed. Effect of rotating speed, potential and steel hardness has been considered. © 2010 by NACE International.

Abstract
This paper deals with erosion-corrosion of steel in contact with flowing fresh concrete. Results of tests performed in fresh mortar on rotating cylindrical and disk electrodes are reported. The fresh mortar was manufactured by using chemical admixtures in order to retain constant workability during long time tests. Electrochemical and weight loss tests were conducted. SEM analysis was carried out to evaluate damage morphology. Damage mechanisms and corrosion behavior are discussed. Effect of rotating speed, potential and steel hardness has been considered. © 2010 by NACE International.Pubblicazioni consigliate
