Hydrated Lime, also known as Calcium Hydroxide (Ca(OH)₂) or Slaked Lime, is a fine, white, free-flowing inorganic powder widely used across construction, agriculture, water treatment, food processing, and chemical industries. Due to its strong alkaline nature and high purity, hydrated lime plays a critical role in neutralization, stabilization, and purification processes.
Hydrated lime is produced by adding controlled amounts of water to quicklime (calcium oxide) through a process called slaking. This reaction converts quicklime into calcium hydroxide, resulting in a safer, stable, and easy-to-handle powder suitable for industrial applications.
Hydrated lime is manufactured in advanced hydration plants where quicklime reacts with water under controlled conditions. This ensures uniform particle size, consistent chemical composition, and high reactivity. Shaurya Minerals manufactures hydrated lime in state-of-the-art facilities, delivering consistent quality across all grades.
The following table highlights the technical specifications and available grades of hydrated lime powder suitable for various industrial applications.

Answer: Slaked lime is calcium hydroxide, a white, odorless powder made by adding water to quicklime. It is widely used in construction, water treatment, agriculture, chemical processing, and environmental applications due to its strong alkaline nature.
Answer: Slaked lime is produced by hydrating quicklime (calcium oxide) with water. This controlled chemical reaction releases heat and forms calcium hydroxide, which is safe to handle when used correctly.
Answer: Slaked lime is commonly used in:
Construction (plastering, whitewashing, mortar)
Water treatment and pH control
Sugar, paper, and chemical industries
Agriculture for soil conditioning
Wastewater treatment and pollution control
Answer: Yes, slaked lime is safe when handled properly. It is mildly corrosive and can irritate skin or eyes. Always use gloves, goggles, and follow safety guidelines while handling and storing slaked lime.
Answer: Quicklime (calcium oxide) is highly reactive and generates heat when mixed with water. Slaked lime (calcium hydroxide) is the hydrated and more stable form of quicklime, making it safer and easier to use in industrial and construction applications.
Answer: Yes, slaked lime is widely used in water purification to adjust pH levels, remove impurities, and soften hard water. It helps in neutralizing acidic water and precipitating heavy metals.
Answer: Yes, slaked lime is used in agriculture to improve soil quality by reducing acidity, increasing calcium content, and enhancing nutrient absorption for crops.
Answer: Slaked lime should be stored in a dry, moisture-free place in tightly sealed bags or containers. Exposure to air and moisture can reduce its effectiveness over time.
