Design/methodology/approach A systematic literature review was performed, synthesizing findings from microstructural analyses and experimental studies. The methodology focused on key parameters governing performance, including bacterial strains, nutrient...

... the importance of evaluating concrete not solely based on strength but also environmental impact. The study concludes that a multicriteria approach, considering the entire life cycle, is essential for sustainable concrete design, addressing durability, environmental concerns, and economic factors.
