There has been growing interest in self-healing crack repairs using
“inorganic” materials, which is more cost-effective and durable than any
organic repair materials (epoxy or urethane). When concrete experiences
cracks, whatever the cause, it heals by itself using the remaining
anhydrous cement existing within the concrete.
