Atmospheric Corrosion of Reinforced Concrete Steel in Tropical Coastal Regions
Keywords:Concrete, steel reinforced concrete, atmospheric corrosion, chlorides, water/cement ratio.
The influence of atmospheric parameters and chloride deposition rate on concrete using an atmospheric corrosion approach is rarely found in literature. Seven exposure sites were selected in Havana, Cuba and two at Yucatan Peninsula, Mexico, to expose reinforced concrete samples. Two significantly different atmospheric corrosivity levels have been observed after two years of exposure in Havana depending on atmospheric chloride deposition and the w/c ratio of the concretes. Changes in corrosion current are in accordance with changes in chloride penetration and atmospheric chloride deposition. The influence of sulphur compounds deposition should be considered to study atmospheric corrosion of reinforced steel in concretes either in Havana.
