Self-Healing Concrete: Concepts, Energy Saving and Sustainability

The production of cement accounts for 5 to 7% carbon dioxide emissions in the world, and its broad-scale use contributes climate imbalance. As a solution, biotechnology enables cultivation bacteria fungi synthesis calcium carbonate as one main constituents cement. Through biomineralization, which is initial driving force compounds compatible with concrete, crystallization, these can be delivered cracks concrete. Microencapsulation method that serves clock determine when crystallization needed, assisted by control factors such pH aeration. present review addresses possibilities working bioconcrete, describing composition Portland cement, analysis methods, deterioration, well environmental energetic benefits using an alternative material. A discussion on credits also offered. contents this paper could strengthen prospects self-healing concrete way meet high demand contributing building sustainable society.
