High chemical activity: As a strong base, it can quickly undergo neutralization reactions with acids to form corresponding calcium salts and water, and is widely used in scenarios such as acidic wastewater treatment and soil improvement. For example, in acidic wastewater treatment, it can rapidly adjust the pH value of the wastewater to neutral.
Good stability: Under normal storage conditions, it is stable in nature and not easy to decompose or deteriorate. However, it should be noted to avoid contact with acidic substances to prevent chemical reactions.
Strong alkalinity and corrosiveness: It has strong alkalinity and is corrosive to skin and fabrics. Strict protective measures must be taken during use. However, due to its low solubility in water, its hazard level is relatively lower compared with other strong bases.
Strong hygroscopicity: It easily absorbs carbon dioxide in the air and gradually converts into calcium carbonate. This characteristic helps improve the hardening and strength of materials in the application of building materials.
