Calcium Aluminate Powder FAQ
What is the shelf life of calcium aluminate powder?
When stored properly in a dry environment (relative humidity below 60%) within sealed containers, our calcium aluminate powder maintains optimal quality for up to 12 months. The material should be protected from moisture absorption to prevent premature hydration.
How does calcium aluminate powder compare to Portland cement?
Calcium aluminate powder offers significantly faster setting times, higher early strength development, and superior resistance to chemical attack compared to Portland cement. While Portland cement typically contains about 5% alumina, our calcium aluminate powder contains 70-80% alumina, making it ideal for high-temperature applications.
What safety precautions should be taken when handling calcium aluminate powder?
Standard personal protective equipment including dust masks, safety goggles, and gloves should be worn. In case of eye contact, flush immediately with plenty of water for at least 15 minutes. The powder may cause respiratory irritation if inhaled in large quantities, so adequate ventilation is recommended.
