Abstract
The present disclosure discloses a method for improving the performance of concrete aggregates, comprising the following steps: (1) adding composite microbial powders, recycled aggregates and water into a stirring pot in a certain ratio to be continuously and uniformly stirred; (2) placing the recycled aggregate obtained in step (1) and another microbial powder in a vacuum device so as to fill the microbial powder into the cracks of the recycled aggregate in a negative-pressure environment; and (3) spraying a calcium source solution to the surface of the recycled aggregate obtained in step (2) at an interval of 5-6 hours for repeating 3-5 times to maintain the wet surface of the recycled aggregate.
