bio-concrete or self-healing concrete

Self-healing concrete is defined as a type of concrete that exhibits self-healing properties. Self-healing or self-repair of concrete means that the property is subject to repair and repair of the concrete crack by autonomous or autonomous methods.

The properties of concrete that define all of these activities are its durability. Durability is the physical property that helps a concrete shield from physical or chemical attacks. As durability decreases, cracks are more likely to develop.

Some major types of cracks in concrete are settlement cracks, expansion cracks, plastic shrinkage cracks, shear and flexible cracks, cracks caused by reinforcement corrosion, weather cracks, thermal stresses and defective design.

ADVANTAGES OF SELF HEALING CONCRETE:

1. This concrete has a much lower permeability, greater durability and pressure bearing capacity than conventional concrete.

2. It can be applied in spray form to existing buildings, which can reduce the overall repair and maintenance costs of buildings.

3. This is an environmentally friendly technology because the low use of concrete prevents the production of carbon dioxide.

4. SHC is a more effective shock absorber that protects against earthquakes because of the polymer layer on its surface.

5. It can work on an internal level which means it can reach small cracks.

6. Unhydrated cement that does not contribute to a strong partnership can be used.

7. This type of concrete helps to fill cracks.

8. Improving the compressive strength of concrete.

9. Good resistance to freeze-thaw attack reduction.

10. This reduces the permeability of the concrete.

11. Corrosion reduction of reinforced concrete.

12. Also, helps reduce maintenance and repair.
