Lime Mortar
Lime mortar is composed of lime, water, and an aggregate such as sand.
Lime mortar is used for the conservation of old buildings, the recreation of new ones, and, more recently, the creation of sustainable buildings (eco-building).
Market Needs
The main qualities of mortar are that it should provide good adhesion to building units, such as bricks and stones, and should not develop cracks in joints.
Moreover, mortar should be water-resistant and easily workable to ensure high durability and the speed of construction while keeping low costs.
Solutions
Hydrated Lime
During applying mortar
- Increase water retention, leading to better contact and bond with the substrate
- Improve plasticity and workability, making it easier to handle on the trowel
Mortar performance
- Due to the improved contact and bond with the substrate, mortar is more vapor permeable (breathable mortar), reducing the risk of frost damage
- Help the construction withstand the minor structural movements and encourage crack formation to be in the form of gradual micro-cracking within the material
- These micro-cracks can repair themselves naturally by the reaction of hydrated lime and atmospheric carbon dioxide
- Reduce the risk of unsightly efflorescence
