Generating heat for industrial processes creates 17% of global carbon emissions. Cheap firebricks could store renewable electricity for one-tenth the cost of batteries.
Mineral deposits called “lime clasts” found in ancient Roman concrete give the material self-healing capabilities that could help engineers develop more resilient modern concrete and reduce its associated emissions

Besides Roman concrete, several other ancient building technologies could make modern structures more durable and sustainable.
Sadly, the Roman concrete recipe was lost over time, though scientists have been painstakingly trying to recreate the formula for years.
Well, scientists have discovered that ancient Roman concrete had self-healing properties, which is why it was so durable.
This is a great idea! Some ancient Roman structures are still standing, more than a thousand years since they were built.
