Abstract
Methods and compositions are described for concrete repair using a non-naturally occurring or a synthetic catalyst. The catalyst includes an aromatic hydrocarbon having an active zinc ion configured to facilitate interaction between carbon dioxide and water and to precipitate concrete repairing calcium carbonate crystals. The catalyst is an analog of zinc cyclen, zinc and an indole-based molecule, and zinc tris(2-pyridylmethyl)amine (TPA).
