Sea Shells and Bone Could Inspire Stronger, Longer-lasting Concrete, According to New MIT Study

A group of scientists at MIT are taking cues from nature to develop a new type of concrete that may be stronger and more durable than traditional cement. In a recent paper published in the journal Construction and Building Materials, researchers compared cement paste with the structure of natural materials like bones, shells, and sea sponges. Researchers noted that naturally occurring structures like shells are exceptionally strong because of the way they are arranged at both the microscopic level as well as the ‘macro’ (visual) level. Read more.
