Oyster cement: Scientists study shellfish to make stronger, faster-curing building material

Want stronger concrete? Just add oysters.

Concrete is everywhere, and that’s a problem. Manufacturing the essential material accounts for around eight percent of annual global carbon dioxide emissions, making it one of the single biggest contributors to the climate crisis. Researchers are investigating all types of creative solutions to the issue, often by replacing ingredients with more eco-friendly alternatives. Recent propositions include adding coffee grounds, bacteria, and even rec…

Oyster cement: Scientists study shellfish to make stronger, faster-curing building material

Building upon the chemistry that oysters use in miles-long reefs, scientists have found a way to create cement that is stronger and cures faster. Jonathan Wilker, a professor of chemistry in Purdue University's College of Science and an expert in adhesives and biomimetic materials innovation, has long been interested in formulating new, more sustainable and better materials. Recent work from his research group has included using nature as an ins…
