Title: Durability of Concrete to Marine Environment
Author(s): J. Beslack
Publication: Special Publication
Appears on pages(s): 599-608
Keywords: chlorides; corrosion (biological, chloride); durability; freeze-thaw durability; marine atmospheres; sea shells; Materials Research
Abstract:The biological effects and chloride penetration studies were carried out on a 10-year-old concrete structure of the arch bridge on the island Krk in the North Adriatic. Concrete cores of 100 mm diameter were drilled from three main locations of the structure and tested for chloride content at depths 0 to 10, 10 to 20, and 20 to 40 mm. The influence of aggressive organisms on the elements below sea level was determined. The biological life of the concrete below sea level was massive, the value being 1300 units per mý at a depth of about 18 m. The shell Recellaria Dubia can make depressions of 5 to 10 mm diameter.
