Bendable concrete inches closer to reality

Bendable concrete, with a design inspired by seashells, can make U.S. infrastructure safer and more durable.


Spring construction season is underway, and many tons of concrete will be used in the coming months. Unfortunately, concrete is a brittle material: Placed under stress, it cannot bend very far before it fractures. Some pavements that are being poured now will crack within a few years and require expensive repairs. New concrete will be mixed, and the cycle will start again.

But a better solution is in view. My laboratory at the University of Michigan, along with many other laboratories around the world, has shown it is possible to make concrete more ductile – that is, bendable without fracturing. Bendable concrete makes infrastructure safer, extends its service life and reduces maintenance costs and resource use.
