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).

An adhesive for moss and a method for preparing the adhesive are provided, wherein the method includes steps of: adding melamine, urea, attapulgite and sepiolite powder into a ball milling tank, and adding milling balls into the ball milling tank for ball milling; then collecting ball-milled materials; adding konjac glucomannan, chitosan and collagen into water and stirring, wherein during stirring, half of the ball-milled materials are added into the water; then adding latex powder, stearic acid and ammonium zirconium carbonate, and stirring, wherein during stirring, the other half of the ball-milled materials are added into the water. The adhesive for moss can be used for bonding moss with sufficient bonding effect, which is environment-friendly and will not harm the moss; meanwhile, the konjac glucomannan, the chitosan, the collagen attapulgite and the sepiolite powder which are contained in the adhesive can provide nutrition for the moss.
