Biocement generated by bacteria, also known as self-healing concrete, is a technology that incorporates certain bacteria into concrete mixtures. These bacteria lie dormant until cracks form in the concrete. When water enters these cracks, it activates the bacteria, which produce limestone to fill the gaps and heal the concrete.
The application of cement-generated bacteria has several benefits:
1. Self-healing properties:
It helps to prolong the lifespan and durability of concrete structures by automatically repairing cracks, reducing maintenance costs, and increasing their overall structural integrity.
2. Environmental sustainability:
The self-healing process reduces the need for repairs and replacements, leading to lower consumption of resources and construction waste.
3. Infrastructure resilience:
Self-healing concrete can enhance the resilience of critical infrastructure such as bridges, roads, and buildings, making them more capable of withstanding wear and tear over time.
Durable and sustainable infrastructure is in high demand, which drives up the price of self-healing concrete. As cities grow and existing structures age, there is a greater emphasis on cost-effective and eco-friendly construction materials. Self-healing concrete addresses these concerns and presents an attractive solution for developers and governments.
