Reinforcing method of recycled concrete

The invention discloses a reinforcing method of recycled concrete, and belongs to the technical field of biology, the reinforcing method comprises the following steps: preparing a culture medium; inoculating and culturing: inoculating a bacillus pasteurii seed solution into the culture medium, and culturing at a constant temperature of 30 DEG C and a stirring speed of 180rpm; introducing compressed air for aerobic culture, and obtaining a bacillus pasteurii culture solution; Mineralization reinforcing: the concrete regeneration particles are soaked in a diluted bacillus pasteurii culture solution for 1-3 h, then mineralization treatment is conducted, in the mineralization process, the bacillus pasteurii culture solution is circulated through a feed liquid pump, urea and calcium nitrate are added at the same time, and therefore a mineralization solution with the concentration of the urea and the concentration of the calcium nitrate being 0.6-0.9 mol/L is obtained, and the temperature of the mineralization solu
