Zusammenfassung:	The present invention relates to a strengthening method for a recycled aggregate using biological deposition, comprising the following steps: (1) filling and soaking: in a vacuum environment, soaking a recycled aggregate in a bacterial solution, then taking out the recycled aggregate from the bacterial solution, soaking in a mineralized culture solution, taking out the recycled aggregate after the soaking is finished, and cleaning and drying; (2) repairing and soaking: taking out the recycled aggregate treated in step (1), cleaning and drying, then soaking in a mixed culture solution of the bacterial solution and the mineralized culture solution; wherein the bacterial solution contains bacillus. In the present invention, the strengthening method for a recycled aggregate using biological deposition can better target areas needing to be repaired of the recycled aggregate, thereby obtaining a better repairing effect, and a bacterial powder produced by industrial production is used to greatly reduce process costs
