California bridge could transform industry with nanocrystals

Construction Connect » A new bridge will be built in California this summer. That’s hardly earth-shattering news. But this one will be different. Thanks to the work of researchers at Purdue University, this bridge will use concrete that has been infused with microscopic-sized nanocrystals from wood. The idea is that the nanocrystals will make the concrete stronger so that less of it is needed.
