Lime Putty
£94.99Call to Order
Lime Putty 15 Litre (approx 20 Kg)
Limestone (Calcium Carbonate – CaCO3) is burnt in a kiln giving off Carbon Dioxide (CO2) gas and forming Calcium Oxide (CaO) which is commonly known as Quicklime. It needs to be burnt at 900-1100°C to ensure a good material is produced. The resulting lime is at its most volatile and dangerous at this stage.
The Burnt Lime or Quicklime is then combined with water (slaked) as quickly as possible. Combining Quicklime (CaO) and water (H20) produces Calcium Hydroxide (Ca(OH)2 – slaked lime and heat. It is combined with an excess of water which produces a putty. It is also known as non-hydraulic lime because it requires exposure to air in order to carbonate and does not set under water.
