Description
Hydrated Lime (Slaked Lime)
What is Hydrated Lime?
Hydrated lime, also commonly known as slaked lime, is a versatile, fine white powder produced by adding water to quicklime (calcium oxide). This process creates calcium hydroxide, a highly adaptable material used across construction, industrial, and environmental applications.
Uses in Construction
- Hydrated lime is widely used in building and construction, particularly when combined with cement to create mortar and plaster mixes.
- It enhances workability, improves bonding strength, and increases flexibility, helping to reduce cracking over time. This makes it a valuable ingredient for both traditional and modern construction methods.
Industrial and Commercial Applications
- Beyond construction, hydrated lime serves a broad range of industrial purposes, including:
- Soil stabilisation: Improves the strength and durability of road base materials and subgrades.
- Asphalt production: Enhances performance and extends the lifespan of asphalt surfaces.
Steel manufacturing: Plays a role in refining and purifying metals during production processes.
Water and waste treatment: Commonly used for pH control and neutralisation of acidic substances.
Environmental Benefits - Hydrated lime is also widely used in environmental management. Its neutralising properties make it effective in treating wastewater, controlling odours, and reducing pollutants. It is an essential material in processes aimed at improving water quality and managing industrial emissions.
Key Benefits of Hydrated Lime
- Improves workability and durability in mortar and plaster
- Enhances soil strength for construction and roadworks
- Supports efficient industrial processing
- Effective for pH regulation and neutralisatio
- Multi-purpose and cost-effective solution
