Experimental concrete that patches up cracks by itself is to undergo outdoor testing.
What amazing potential this material has! It is exciting to see that innovations in building materials can come from such surprising fields as microbiology. Of course, when you consider how much of our building materials are naturally occuring, perhaps we should expect more advances for building from the scientists working with microbes!
The implications of this advancement could be incredible. Imagine the savings on maintenance and the reduction in traffic disruptions in major urban areas that would result from the successful commercialization of this concrete! Beyond streets, this material would be highly desirable in other structures as well!
