Techniques to Increase Bio Brick Strength

Bio-brick production using microbial cementation involves compacting a mixture of powder and microorganisms, followed by controlled liquid application for rapid cementation. The process produces bio-bricks with enhanced mechanical strength compared to conventional cementation methods. The microorganisms catalyze carbonate precipitation in the pore spaces, creating a self-healing material that achieves high compressive strength (over 4MPa) without the need for traditional cement. The bio-bricks can be produced using a novel, compacting-liquid-feeding approach that balances microorganism concentration with cement volume.
