Bones and shells could produce more durable concrete 26th May 2016

Researchers at MIT are seeking to redesign concrete by following nature's blueprints. In a paper published online in the journal Construction and Building Materials, the team contrasts cement paste with the structure and properties of natural materials such as bones, shells, and deep-sea sponges. As the researchers observed, these biological materials are exceptionally strong and durable, thanks in part to their precise assembly of structures at multiple length scales, from the molecular to the macro, or visible, level.
