Summary: | The invention discloses a high-performance green water permeable brick based on facultative aerobic microorganism mineralization and a preparation method thereof. The high-performance green water permeable brick comprises the following components: a facultative aerobic microorganism-loaded recycled aggregate, a natural aggregate, cement, a facultative aerobic microorganism suspension, fly ash, water and calcium lactate. In the preparation process, facultative aerobic microorganisms are used as a performance reinforcing agent, and two doping modes of directly doping microorganisms and indirectly doping microorganisms by taking the recycled aggregate as a carrier are adopted. In an aerobic environment, facultative aerobic bacteria are subjected to aerobic metabolism to generate calcium carbonate precipitates to repair cracks and holes of the recycled aggregate, and a weak bonding area between the recycled aggregate and a new cement matrix is enhanced; in an anoxic environment, facultative aerobic bacteria are s |
