Product Description: Our Calcium Hydroxide is a fine white powder with excellent chemical properties. It is widely used in various industries due to its versatile nature and exceptional performance. This compound is known for its high purity and quality, making it suitable for a wide range of applications.

Usage and Application:  

Calcium hydroxide, also known as slaked lime or hydrated lime, is a chemical compound with various applications across different sectors. This article aims to provide a comprehensive overview of the applications and uses of calcium hydroxide in diverse industries. From construction and agriculture to food processing and wastewater treatment, calcium hydroxide plays a vital role in enhancing processes, improving products, and promoting sustainability.

  1. Construction Industry:

1.1 Cement and Mortar: Calcium hydroxide is used in the production of cement and mortar. It reacts with carbon dioxide from the air to form calcium carbonate, which strengthens and stabilizes the concrete structures.

1.2 Soil Stabilization: In construction projects, calcium hydroxide is employed to stabilize soil. By treating soil with calcium hydroxide, its plasticity and compressibility can be reduced, providing a stable foundation for buildings, roads, and other infrastructure.

1.3 Efflorescence Control: Calcium hydroxide is used to control efflorescence in construction materials such as bricks and concrete blocks. It reacts with soluble salts, preventing their migration to the surface and minimizing the formation of unsightly white deposits.

  1. Agriculture:

2.1 Soil pH Adjustment: Calcium hydroxide is commonly used in agriculture to adjust soil pH. It can neutralize acidic soils, promoting optimal conditions for plant growth and enhancing nutrient availability.

2.2 Liming: As a source of calcium, calcium hydroxide is used for liming soil. It helps neutralize soil acidity, improves soil structure, and provides essential nutrients for plants, ultimately enhancing crop yields.

2.3 Fungicide and Pesticide: Calcium hydroxide can act as a fungicide and pesticide in agricultural applications. It helps control certain plant diseases, such as damping-off and blossom-end rot, and acts as an insect repellant.

  1. Water Treatment:

3.1 Drinking Water Treatment: Calcium hydroxide is used in the treatment of drinking water. It aids in the removal of impurities, such as heavy metals and organic contaminants, by forming insoluble precipitates that can be easily filtered out.

3.2 Wastewater Treatment: In wastewater treatment plants, calcium hydroxide is utilized as a flocculant and pH adjuster. It helps precipitate impurities and regulate pH levels to facilitate the removal of pollutants and ensure the efficiency of the treatment process.

3.3 Softening Agent: Calcium hydroxide is employed as a softening agent to reduce water hardness. It reacts with dissolved minerals, such as calcium and magnesium ions, forming insoluble precipitates that can be removed, thus preventing scale formation in pipes and appliances.

  1. Food Processing and Preservation:

4.1 Pickling Agent: Calcium hydroxide is used as a pickling agent in food processing. It helps maintain the firmness and crispness of fruits and vegetables during the pickling process.

4.2 Food Additive: Calcium hydroxide is an approved food additive used for various purposes. It acts as a pH regulator, firming agent, and nutrient supplement in products such as canned fruits, vegetables, and beverages.

4.3 Corn Processing: In corn processing, calcium hydroxide is used in a process called nixtamalization. It helps soften corn kernels and improves their nutritional value, making them more suitable for the production of masa flour and tortillas.

  1. Environmental Applications:

5.1 Flue Gas Desulfurization (FGD): Calcium hydroxide is utilized in flue gas desulfurization systems to remove sulfur dioxide from industrial exhaust gases. It reacts with sulfur dioxide to form calcium sulfite or calcium sulfate, which can be safely disposed of or further processed.

5.2 Acid Neutralization: In industries where acidic waste streams are produced, calcium hydroxide is employed for neutralization. It helps raise the pH levels, reducing the harmful effects of acidic pollutants before their discharge into the environment.

  1. Other Applications:

6.1 Dental Applications: Calcium hydroxide is used in dentistry for various applications, including pulp capping and root canal treatment. It has antimicrobial properties and promotes dentin bridge formation, aiding in the preservation of tooth structure and dental health.

6.2 Leather Tanning: In leather processing, calcium hydroxide is used in the lime-sulfide process. It helps remove hair and flesh from animal hides, facilitating the tanning process and preparing the hides for further treatment.

6.3 Paper Manufacturing: Calcium hydroxide is employed in the paper industry as a filler and coating material. It enhances paper quality, improves brightness, and contributes to the paper’s strength and durability.


Calcium hydroxide, with its diverse applications and uses across multiple sectors, plays a crucial role in various industries. From construction and agriculture to water treatment and food processing, calcium hydroxide enhances processes, improves products, and contributes to sustainability. Its properties as a pH adjuster, flocculant, and nutrient supplement make it a valuable compound in water treatment and agriculture. Additionally, in construction, food processing, and environmental applications, calcium hydroxide demonstrates its versatility and importance.
