Aerial lime

Aerial lime, also known as air lime or quicklime, is a type of lime produced by heating limestone in a kiln. It is called "aerial" because it is primarily used in its dry powder form and reacts with carbon dioxide in the air to form calcium carbonate, a process known as carbonation. This reaction allows aerial lime to harden and set, making it suitable for various construction and building applications.

Aerial lime has been used for centuries in traditional building practices and is known for its excellent workability and durability. It is often used as a key ingredient in lime mortars, plasters, and renders, providing a breathable and flexible material for construction. Aerial lime has the ability to absorb and release moisture, allowing for natural moisture regulation within buildings and reducing the risk of trapped moisture and associated damage.

Due to its properties, aerial lime is favored for restoration and conservation work, particularly in historic buildings, as it closely replicates the original materials and techniques used in traditional construction. Its use promotes the sustainability and longevity of buildings by allowing moisture to evaporate and preventing moisture-related issues such as mold growth and deterioration.

Overall, aerial lime is valued for its compatibility with historic structures, its environmentally friendly nature, and its contribution to the preservation of traditional building methods. It continues to be an essential material in the field of architectural conservation and is appreciated for its unique properties and aesthetic appeal.
