Calcium oxide is quicklime It can absorb water and turn into calcium hydroxide, which is commonly used for drying other things Good for environmental disinfection in medicine. It is mostly used in construction, brewing walls with it. Over time, it absorbs carbon dioxide and becomes strong calcium carbonate

Calcium oxide is alkaline and can react with glassy activated silica or activated alumina at room temperature to produce hydraulic products and bond. Therefore, calcium oxide is an important raw material in the building materials industry. However, the function of calcium oxide is not limited to this. After absorbing moisture or adding water, quicklime can become hydrated lime, which can be mixed into stone mortar, lime paste, and lime mortar as coating materials. In addition to being used as building materials, it can also be used as filling materials in rubber, plastics, paper, toothpaste, and cosmetics. At the same time, calcium oxide can also be used as a desiccant and disinfectant, which is widely used in daily life. In agricultural production, quicklime can also be used as fertilizer. After blending quicklime, it can improve soil structure and supplement calcium for plants.
