High calcium hydrated lime Ca(OH)2 is a dry powder produced by combining quicklime with a sufficient amount of water to satisfy the quicklime's natural affinity for moisture. This process, known as slaking, converts CaO to Ca(OH)2.
The amount of water required for slaking depends on both the particular characteristics of the quicklime and the type of hydrating equipment available. Hydrated lime easily forms as a suspension or slurry and is often pumped to multiple process locations within industrial plants. The resulting solution is strongly alkaline, having a pH of 12.4. Most hydrated limes contain approximately 75% CaO and 25% H2O.Applications
- Water treatment: Hydrated lime is used to neutralize acidic water and remove impurities, making it suitable for drinking and industrial use.
- Asphalt pavement: Hydrated lime acts as an anti-stripping agent in asphalt, preventing the separation of asphalt binder from aggregate stones under moisture stress.
- Soil stabilization: Hydrated lime is used to improve the stability and workability of soils, particularly for road construction and foundation work.
- Food processing: Food-grade hydrated lime is used in various food applications, such as preventing the lumping of dried ingredients and regulating acidity.
Standards
Graymont carefully monitors its production processes to provide products that meet exacting specifications. These include applicable ASTM, NSF-60, and AWWA B202 standards.
