Study seeks to extend life of concrete structures using bacteria

A study led by the University of Ghent in Belgium and sponsored by the European Union is developing new technology that combines "limestone-producing bacteria" with concrete. The intent is to combat the effects of water and chemicals on concrete and thus extend the life of structures. "As the water seeps into the concrete, the bacteria will activate and start producing limestone, which will mend the cracks before they become a threat to the structure," said Carola Edvardsen, a concrete expert for engineering consulting firm Cowi.
