Deterioration of concrete in cold sea waters
The disruptive conditions of concrete exposed to cold sea water in the tidal zone are examined. They are the result of the combination of physical and chemical processes, one enhancing the other. Wetting and drying, freezing and thawing as thermal shocks generate microcracks and allow further saturation and deeper penetration of aggressive ions. These ions, in return, will react with the cement paste and disrupt further the concrete surface. Mineral additives, by densifying the matrix and improving the interface paste-aggregate, reduce the disruption of the conrete. Silica fume appears to be more efficient than blast furnace slag.
