| In some embodiments, alternate sources of aluminum or calcium are provided in various ways including the desired compounds. The further object of the present invention contemplate in situ creation of the compound in interest in fresh concrete and as a slurry which can be employed in remediation of existing concrete structures. A method of resisting corrosion in concrete containing metal elements is provided. It includes introducing into fresh concrete, containing metal elements, at least one compound capable of sequestering chloride ions. The method may also involve employing a compound which is capable of establishing a corrosion resistant oxide layer on the metal reinforcing elements. The invention also includes certain compounds which may be employed in the method as well as concrete structures containing the compounds. In another embodiment of the invention, concrete structures may be rehabilitated by providing an overlay containing a compound of the type which will contribute to corrosion resistance either through chloride ion sequestering or creating barriers around metal structural elements with the overlay being provided in situ or as a preformed member and with possible use of a slurry in combination with an overlay segment. In another embodiment, a source of alumina is combined in solution with Ca(NO2)2 and/or NaNO2 with the resultant solution being introduced into the pores of a concrete structure, preferably under pressure to cause them to react with each other and with Ca(OH)2 contained within the concrete to produce the desired corrosion inhibiting compound. | ||||||

| The present invention provides methods and compounds for the in situ formation in concrete of chloride sequestering compounds that resist corrosion of metals contained within the concrete. These chloride sequestering compounds may include, but are not limited to, compounds having the formula 3CaO.Fe(2-x)AlxO3.Ca(NO2)2.nH2O and 3CaO.Fe(2-x)AlxO3.Ca(NO3)2.nH2O, where x ranges from about 0 to 1.4 and n ranges from about 8 to 24. In one embodiment, at least one Fe-containing additive is introduced into cement, and at least one anion-containing additive is introduced into mixing water. When the cement and mixing water are combined to create fresh concrete, the additives react to form chloride sequestering compounds. In another embodiment, the additives are introduced or mixed directly into fresh concrete that has already been formed, where they react to create chloride-sequestering compounds. “In situ” formation refers to the creation of a chloride sequestering compound within concrete. | ||||||
