Hydrated lime

Hydrated lime, also known as slaked lime or calcium hydroxide (Ca(OH)2), is a chemical compound formed by mixing water with quicklime (calcium oxide). The process of mixing water with quicklime is called slaking, and it results in a chemical reaction that produces heat and converts the quicklime into a fine, white powder known as hydrated lime.

Hydrated lime has several applications across various industries. In construction, it is commonly used as a key ingredient in mortar, plaster, and stucco mixtures. It provides improved workability, adhesion, and durability to these building materials. Hydrated lime is also utilized in soil stabilization and as a component in the production of asphalt and concrete.

In the water treatment industry, hydrated lime is used for pH adjustment and coagulation purposes. It helps to neutralize acidic water and remove impurities by precipitating them out. Additionally, hydrated lime is employed in wastewater treatment processes to control odor and facilitate the removal of heavy metals and other contaminants.

Agriculture is another sector where hydrated lime finds application. It is commonly used to modify soil pH and improve nutrient availability. Hydrated lime can be applied to acidic soils to raise the pH level, creating a more favorable environment for plant growth. It is also used as a component in livestock feed and as a disinfectant in animal husbandry.

Hydrated lime is known for its alkaline properties, and it should be handled with caution. It can cause skin and eye irritation, so appropriate safety precautions should be taken when working with it.

Hydrated lime is a versatile chemical compound with a wide range of applications. Its properties make it valuable in construction, water treatment, agriculture, and other industries where pH adjustment, coagulation, or soil modification is required.
