Biobased tech gives concrete healing powers
The Basilisk Self-Healing Agent is an admixture that contains dormant bacterial spores and nutrients. When a crack forms and water gets in, the bacteria activate and produce calcium carbonate, which seals cracks up to 1 mm wide with no human intervention.
Prof. Dr. Henk Jonkers developed the technology at Delft University of Technology in the Netherlands.
“Ready-mix producers are the link between a specification and a finished structure,” said Anna Jensen, Chief Operating Officer of Restoration Partners. “Self-healing concrete has a proven record in Europe and Japan. ConcreteWorks gives us the chance to show U.S. producers how it fits into the mix designs, batching and delivery routines they already use, and how it can help them offer engineers and owners more durable, watertight concrete.”
