Magnesium Attack of Cementitious Materials in Marine Environments
Concrete undergoes numerous chemical reactions with the chemicals in a marine environment. While sodium chloride is the dominant salt in marine waters, there is also a substantial amount of magnesium sulfate. The attack by the Mg ion is particularly dangerous for the system, as it can cause a complete disintegration of the C-S-H in the long term. However, in the presence of a strong chloride environment such as in seawater, there are some differences in the mechanism of magnesium attack as opposed to a typical sulfate attack. This chapter explores the chemistry of magnesium and sulfate attack in a chloride environment.
