Cultivation of microalgae in calcium and phosphate-rich wastewater as a substitute nutrient medium for crack healing in cement-mortar using microbially induced calcite precipitation (MICP) method

Key Points

• Crack healing in cement-mortar is effectively achieved using microalgae cultivation, showing promising results.
• The study demonstrated 85% mineral precipitation through microbially induced calcite precipitation (MICP).
• Cultivation occurred in calcium and phosphate-rich wastewater, providing a sustainable nutrient medium for algae growth.
• The findings highlight the potential for using wastewater as a resource to enhance concrete durability and reduce environmental impact.
