Astra Lime / Slow Reaction – High-Quality Calcium Oxide for Industrial Use from Astra Mining
Astra Lime / Slow Reaction is a premium calcium oxide (CaO), also known as quick-burning lime. It is created by heating limestone (CaCO₃) in vertical kilns at 1250°C to 1300°C. This process, called calcination, breaks down calcium carbonate into calcium oxide (CaO) and carbon dioxide (CO₂). As a result, the product becomes a fine, high-quality powder with excellent flowability. Additionally, its reaction time with water is slow, ranging from 3 to 15 minutes (R 60).
Exceptional Quality and Unique Features
Astra Lime / Slow Reaction contains 92% calcium oxide, which ensures strong performance in various applications. Since it reacts slowly with water, industries can achieve better control over hydration processes. This feature makes it perfect for applications where gradual moisture absorption is required.
Moreover, this product plays an essential role in white brick and aluminum manufacturing. It helps improve quality, durability, and strength, making construction materials more reliable. Thanks to its specialized chemical composition, it delivers stability and efficiency, making it a preferred choice for many industries.
Key Applications and Benefits
Astra Lime / Slow Reaction is widely used in the construction and aluminum industries. Its key benefits include:
- Enhancing White Brick Quality – It reduces cracks, which leads to stronger and longer-lasting structures.
- Boosting Fire Resistance – It increases heat resistance, making bricks more durable in high temperatures.
- Supporting Gradual Drying – It helps bricks dry evenly, which prevents structural damage.
- Increasing Whiteness – It produces brighter, more uniform-colored bricks, which improves their appearance.
- Ensuring Excellent Flowability – Its fine powder texture allows for smooth application and easy handling.
