Self-healing concrete contains bacteria and starch that allow it to automatically repair cracks by secreting a bioplastic material. Unlike regular concrete, self-healing concrete is able to repair itself without external treatment. Homeostatic facades consist of flexible materials that change shape on their own to reduce solar heat gain. Artificial spider silk is a unique combination of proteins that could be used in construction. 3D printing uses computer-controlled nozzles to extrude molten plastic in precise patterns for construction applications.

3. Self-healing concrete
• Self-healing concrete is a new type of concrete. It imitates the
automatic healing of body wounds by the secretion of some kind of
material.

4. How it works?
• Unlike regular concrete, self-healing concrete contains bacteria called
bacillus pasteurii, along with a form of starch that serves as food for
the bacteria. These bacteria stay dormant in the concrete until a crack
forms and air gets

5. bioplastic
• Bioplastics are a type of plastic that can be made from natural
resources such as vegetable oils.
• Since bioplastics are plant-based products, the consumption of
petroleum for the production of plastic is expected to decrease by
15–20% by 2025.

7. Homeostatic facades

8. • The line maze like facade consists of material that flexes and bends as
an artificial muscle fighting solar heat gain by changing shape on its
own.

9. Artificial spider silk
• They are composed of a unique combination of spider silk protein
and silkworm silk protein.

10. 3d printing construction
• A 3D printer essentially works by extruding molten plastic through a
tiny nozzle that it moves around precisely under computer control.
