Michelle Pelletier, a University of Rhode Island master's degree candidate from Woonsocket, Rhode Island has embedded a microencapsulated healing agent directly into a concrete formulation enabling it to 'heal.' When tiny stress cracks begin to form in the concrete, the embedded healing agent reacts with other concrete components to produce crack-filling goo that hardens in about a week.
The self-healing concrete formula may also be less corrosive to the metal reinforcement bars commonly used in concrete construction. "If self-healing concrete can lengthen the life of the concrete and reduce maintenance and repairs, it will ultimately reduce the production of excess amounts of concrete and result in a decrease in CO2 emissions," Pelletier said.
