Lime For Building: Types, Properties, Uses
Soucing the best quality Lime for construction and building material
In the construction of buildings, lime is a highly versatile material. It can be used as a component of the mortar or of the masonry unit, exterior (stucco), and interior plaster systems in masonry applications. In applications like hemp and strawbale construction techniques, lime products may also be employed as a component of mixes and mortars.
Lime in building industry is used for various purposes such as:
- A matrix for lime concrete used in building foundations and filling where early setting is not required,
- For preparing mortar for bedding bricks and stones in masonry works,
- As a cementing material in plaster for covering walls and pointing in preserving joints, and
- For white washing and colour washing.
A good quality lime for construction and building should own the following properties:
- It should possess good plasticity.
- It should be flexible and easily workable.
- When used in mortar, it should provide greater strength to the masonry.
- It should solidify in less time and become hard.
- It should comprise of excellent binding properties which adhere to brick or stone masonry units perfectly.
- It possesses high durable properties as it is less shrinkable when used in mortar.
- It should be highly resistant to moisture and can be used for pointing works.
Different types of limes are used for building construction such as: Quick Lime, Slaked Lime/ Hydrated Lime, Fat Lime, Hydraulic. SHC Techmicom is the manufacturer and exporter of Quick Lime and Hydrated Lime at export standard for construction and building material.
1. Quick Lime:
Quick lime is also called caustic lime (Calcium Oxide). This is produced by burning pure limestone (Calcination process). It is the cheapest form of lime available which is highly amorphous and caustic. Quick lime has a great affinity towards moisture.
Quick lime is one of the key ingredients in the manufacture of cement.
2. Hydrated Lime:
Slaked lime is obtained by the process of slaking, where quick lime is combined with water. Slaked lime is also known as Hydrate of lime.
This is highly suitable for mortar applications. It can also be used in plastering works and in cement as a binder.
