Construction Material & Lime
Lime has been used in building techniques for over the 5000 years. Lime is recognized for its resilience, durability, and water-resistant qualities. Lime and its derivatives, is commonly used in making mortar and plaster, and in the manufacturing of Autoclaved Bricks, Light Blocks, as well as the Insulated Blocks.
- For Lime mortars, it is recommended for use with existing mortar of a similar type or reconstruction of buildings. It is lime putty mixed with sand. It can be used to bed in masonry, and is also used in pointing or rendering brickwork, and for general plastering use.
- Plaster is a building material used for the protective and/or decorative coating of walls and ceilings and for molding and casting decorative elements. The most common type of plaster mainly contains lime. It is a mixture of calcium hydroxide and sand (or other inert fillers). Carbon dioxide in the atmosphere causes the plaster to set by transforming the calcium hydroxide into calcium carbonate (limestone). It is manufactured as a dry powder and is mixed with water to form a stiff but workable paste immediately before it is applied to the surface.
- As Lime wash, it is usually lime putty diluted in water. This is used to paint internal and external walls. A pigment can be added to create a color wash.
