Definition

Hydrated Lime is calcium hydroxide, a dry powder obtained by treating quicklime with water.

Purpose

Hydrated lime is used in construction, agriculture, and water treatment. In construction, it improves the workability and strength of mortar and plaster. In agriculture, it adjusts soil pH. In water treatment, it removes impurities.

Examples of Use

1. Mortar and Plaster: Enhancing the properties of construction materials.
2. Soil Stabilization: Adjusting soil pH and improving soil structure.
3. Water Treatment: Removing impurities and softening water.
4. Agriculture: Reducing soil acidity to improve crop yields.

Related Terms

• Quicklime: Calcium oxide, a precursor to hydrated lime.
• Lime Mortar: Mortar that includes hydrated lime for improved workability.
• Limewash: A coating made from hydrated lime, used for painting and protecting surfaces.

Notes

Hydrated lime should be handled with care, as it can cause skin and eye irritation. Proper storage in a dry environment is necessary to prevent it from reacting with moisture.
