Roman concrete's 2,000-year durability secret finally decoded
The exceptional strength comes from 'hot mixing' quicklime directly with volcanic ash at high temperatures. This creates distinctive lime clasts that grant remarkable self-healing properties - when cracks form, water reacts with these clasts to form calcium carbonate that naturally repairs damage.
