Application of Biomimicry in civil sector for making new type of cement for buildings by the way corals build reefs

1. CEMENT SIMILAR
TO COMPOSITION
TO CORALS

2. WHAT IS BIOMIMICRY?
• Biomimicry is the term used to describe the substances,
equipment, mechanism and systems by which humans imitate
natural systems and designs. The word biomimicry Originates
from the Greek words:-
Bios = Life
Mimesis = Imitate

3. OUR APPROACH TO BIOMIMICRY
• Cement having composition of Corals -
Bio mineral mineralization expert Brent Constantz of Stanford university was
inspired to make a new type of cement for buildings by the way corals build reefs.
• Concrete represents incredible reservoir.

4. WHAT'S NEWABOUT THIS PROCESS?
• Calcium carbonate precipitation
• The concrete allows us to build massive structures just like the Great Barrier Reef.
• The barrier reef represents billions of tons of carbon dioxide that’s been taken from
the ocean.

5. CONCLUSION
• Tests give evidence that coral like forms can be used effectively in construction
• Coral like cement is used all over the world to give an aesthetic look to exposed
parts of a structure.
