Frequently Asked Questions

Q: What is the difference between Quicklime and Hydrated Lime?

Quicklime (CaO) is produced by calcining limestone at high temperatures, while Hydrated Lime (Calcium hydroxide) is created by adding water to Quicklime (slaking), resulting in a white powder that is easier to handle in some applications.

Q: How does lime help in agriculture?

Lime acts as a soil conditioner by neutralizing acidity (increasing pH), which improves nutrient availability and enhances the overall yield and quality of crops.

Q: Can lime be used for water purification?

Yes, lime has a strong purification effect by absorbing harmful substances and heavy metal ions, making it effective for treating contaminated water environments.

Q: What safety precautions should be taken when handling lime?

Because lime is a strong alkali and can be corrosive, it is essential to avoid direct contact with the skin and respiratory tract. Protective gear such as gloves and masks are highly recommended.

Q: Which industries utilize limestone as a raw material?

Limestone is widely used in the production of glass, steelmaking, rubber, plastics, paper, cosmetics, toothpaste, and the manufacturing of soda ash.

Q: What role does lime play in the construction industry?

Lime is a primary ingredient in mortar and limestone-based materials, providing essential properties such as waterproof capability, moisture resistance, and heat preservation.
