Description
Calcium Hydroxide is an inorganic lime product with the chemical formula Ca(OH)₂. It is also known as Hydrated Lime, Slaked Lime or Portlandite. Manufacturers produce it by adding water to calcium oxide in a process called lime slaking.
This product is a fine, white and odourless powder. It has alkaline properties and dissolves slightly in water. Because of these properties, many industries use it for pH control, acid neutralisation, water treatment and chemical processing.
In construction, Calcium Hydroxide plays an important role in lime mortar, lime plaster, lime paint and sand-lime brick production. It helps improve workability, moisture control and durability in building materials. In addition, contractors use it to stabilise soil and improve the load-bearing capacity of building ground.
Agriculture is another major application. Farmers use hydrated lime to raise the pH of acidic soils and improve soil quality. As a result, crops can access nutrients more effectively. The product can also support composting, odour control and hygiene in selected agricultural environments.
In water treatment, Calcium Hydroxide helps neutralise acidic water and adjust pH levels. It can also help remove impurities, phosphates, metals and hardness-forming compounds from water. Therefore, it supports municipal, industrial and construction-site water treatment processes.
The mining industry also uses this lime product in important processes. In gold extraction, it helps maintain the correct pH during cyanide leaching. It also neutralises acidic mine water and supports safer water management on mining sites.
In chemical manufacturing, Calcium Hydroxide acts as a neutralising agent, precipitant and raw material for other calcium compounds. It also supports flue gas treatment, wastewater treatment, polymer production, rubber processing, lubricating grease production and selected food-grade applications where approved.
Correct handling remains important because this product is alkaline. Users should store it in a dry area and follow the relevant safety data sheet and site procedures.
MEPPAR supplies Calcium Hydroxide for commercial and industrial customers. The product is suitable for approved use in construction, agriculture, mining, water treatment, chemical processing and general manufacturing.
