In situ formation of chloride sequestering compounds |
| abstract |
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) Al x O 3 .Ca(NO 2 ) 2 .nH 2 O and 3CaO.Fe( 2-x) Al x O 3 .Ca(NO 3 ) 2 .nH 2 O, 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. |
