CARBONATION...
Did you know lime mortar slowly turns back into stone?
When lime mortar is applied, it reacts with carbon dioxide (CO₂) from the air in a process called carbonation.
As carbonation takes place, tiny crystals of calcium carbonate begin to form throughout the mortar. These microscopic crystals grow and interlock between the sand particles, gradually binding the mortar together and increasing its strength.
This crystal growth is one reason lime mortar gains strength slowly over time rather than setting hard all at once like cement.
The result is a breathable, flexible mortar that has helped buildings survive for hundreds of years.
Nature's recycling system:
Stone ➡ Lime ➡ Mortar ➡ Stone again.
