Self-healing concrete - Microsopic
Self-healing concrete - This special type of concrete contains bacteria that can produce limestone to fill in cracks as they form, essentially healing itself. It has the potential to greatly increase the lifespan of structures like bridges and buildings.
Self-healing concrete is a type of concrete that can repair its own cracks without the need for human intervention. This is achieved by adding specific bacteria or other materials to the concrete mixture that can help repair the cracks.
One approach to self-healing concrete is to add bacterial spores to the concrete mixture. When a crack forms, moisture enters the crack and activates the bacterial spores, causing them to produce calcium carbonate, which fills the crack and repairs it.

Self-healing concrete has the potential to greatly increase the lifespan of structures like bridges and buildings, as it can repair cracks before they become a major problem. It also reduces the need for costly and time-consuming repairs, which can be especially beneficial for infrastructure in remote or hard-to-reach locations. However, self-healing concrete is still a developing technology and is not yet widely used in construction.
Self-healing concrete is a type of concrete that has the ability to repair its own cracks and damage without the need for human intervention. One approach to self-healing concrete is through the use of microscopic capsules containing healing agents such as polymers or bacteria.

When the concrete cracks, these capsules rupture, releasing the healing agents into the cracks, which then react and solidify, filling the cracks and restoring the concrete's strength. The use of bacteria in self-healing concrete is particularly interesting, as the bacteria can produce limestone as a by-product, which can further enhance the concrete's strength.

Another approach to self-healing concrete is the use of fibers or particles that are embedded within the concrete mixture. These fibers or particles can react to the presence of water, expanding and filling the cracks as they form.

Self-healing concrete has the potential to significantly extend the lifespan of concrete structures, reducing the need for costly repairs and maintenance. It also has the potential to reduce the environmental impact of concrete production, as it can help to reduce waste and the need for new concrete structures.
