Durable Enviro-Friendly Concrete Lab

The new lab enables engineers to test large concrete specimens in a special environmental chamber that simulates extreme temperatures and humidity. Researchers also will use the lab to study new types of more environmentally friendly concrete. The work aims to reduce the amount of carbon dioxide generated by using green ''binders'' needed to make concrete.

Purdue University is operating a new laboratory to help the nation deal with aging highways, bridges and other infrastructure by developing more durable and environmentally friendly concrete.

The research at the Charles Pankow Concrete Materials Laboratory will focus on reducing cracks in concrete and corrosion of steel rods in reinforced concrete, said Jason Weiss, director of the new Pankow Laboratory.

''A civil engineer who graduates today is being asked, more than ever, to build a long-lasting, durable structure on tighter and tighter budgets,'' he said. ''The Pankow Lab will be instrumental in finding critical solutions, while also providing crucial training for students.''
