    摘要: The present invention provides methods for resisting corrosion of metal elements in concrete, and associated compounds and structures. Acid mine drainage sludge is used as a source of a precursor compound that reacts with a source of anion to form a chloride-sequestering compound. The precursor compound may have the formula 2Me′(II)O·(Y(2−x),Y′x)O3+qMe′(II)O, where at least one of Y and Y′ is present; Y and Y′ are different and are independently selected from the group consisting of Al, Fe, Cr, and not present; Me′ is a cation and is selected from the group consisting of Ca, Ba, Sr, Mn, and Zn; x is a number ranging from 0 to 2; and q is a number ranging from 0 to 2; and combinations thereof. In a preferred embodiment, the precursor compound has the formula 2CaO(Fe(2−x),Alx)O3+CaO.

    摘要: A method of resisting corrosion of metal elements in concrete is provided. It includes introducing into concrete containing metal elements, at least one combination compound capable of sequestering chloride ions having the formula 3Me(II)O.(R,R′)2O3.Me(II)(anion)2.nH2O, where R and R′ are different and are independently selected from the group consisting of Al, Fe and Cr; anion is selected from the group consisting of NO2, NO3 and OH, n is 0 to 24, and Me(II) is a cation and is selected from the group consisting of Ca, Ba, Sr, Mn, Zn and combinations thereof. In one embodiment of the invention, concrete structures may be rehabilitated by providing an overlay containing the combination compound, 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.
