What is shelf life of unopened bag quicklime?

The shelf life of quicklime, also known as calcium oxide or unslaked lime, can vary depending on storage conditions. When stored properly in a cool, dry place, an unopened bag of quicklime can have a shelf life of several years. Here are some factors that can affect the shelf life of quicklime:

Moisture: Quicklime is highly reactive with water and can absorb moisture from the air, leading to its degradation. Therefore, it is crucial to keep the bag tightly sealed and store it in a dry environment.

Temperature: High temperatures can accelerate the chemical reactions that occur in quicklime, reducing its shelf life. It is recommended to store quicklime in a cool place to minimize the impact of temperature.

Exposure to air: Prolonged exposure to air can cause quicklime to absorb carbon dioxide and form calcium carbonate, which is less reactive than quicklime. Therefore, it is important to keep the bag sealed to prevent exposure to air.

Packaging: The quality of the packaging material can also affect the shelf life of quicklime. Bags that are not airtight or have defects can allow moisture and air to enter, compromising the quality of the quicklime.

In general, unopened bags of quicklime can have a shelf life of several years when stored properly in a cool, dry place with limited exposure to moisture and air. However, it is always recommended to check the manufacturer's guidelines for specific storage instructions and shelf life information for the particular product.
