Abstract:
A method of resisting corrosion of metals in a concrete structure comprising,creating a slurry containing at least one compound capable of sequestering chloride ions selected from the group consisting of 3Me(II)O.R2O3.Me(II)(anion)2nH2O where n=0 to 24 and 3Me(II)O.R2O3.Me(II)(anion).nH2O where n=0 to 18, â€ƒwhere Me(II) is one or more divalent cations selected from the group consisting of Ca, Ba, Sr, Mn and Zn; R2 is Al2, Fe2 or Cr2; and â€ƒanion is NO2, NO3, CO3, BO4 or OH, but when Me(II) is Ca, R2 is not Al2, â€ƒpositioning said slurry adjacent to said concrete structure, and â€ƒsequestering chloride ions in said compound.
