High-Calcium Hydrated Lime


Hydrated lime

The amount of water required 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.

Hydrated lime is used in a variety of industrial applications including water treatment, as an anti-stripping agent in asphalt, and in soil stabilization. Some hydrated limes are sold into the food-grade market as well. The product is commonly sold in 50-lb. bags or as a bulk material shipped in pneumatic truck trailers or rail tanker cars.

Graymont carefully monitors its production processes to provide products that meet exacting specifications. These include applicable ASTM, NSF-60 and AWWA B202 standards.
