Technical Data of Kerui Refractory Cement for Sale
Kerui Refractory offers three standard cements, including CA50 (1300-1350℃), CA70 (1580-1560℃), CA80 (1750-1800℃). It is all called calcium aluminate cement. The main difference between them lies in the varying content of aluminum dioxide. Within these three types, each one is further subdivided. The main distinction is in the different chemical composition content. Please choose the appropriate types based on your needs.

Introduction of Kerui Refractory Cement
Kerui refractory cement is mainly made of bauxite and other components. It is a new type of high-temperature resistant material. And it is a water-hardening cementitious material with an alumina content of over 50%. So, it has excellent heat resistance performance. It is widely used in high-temperature industries as a high-quality additive material or adhesive. And it also is the the refractory castable.

Factors for Selecting Suitable Refractory Cement
Ingredients
Different ingredients affect the performance of refractory cement. A higher content of alumina can enhance refractoriness and high-temperature resistance. Silica helps improve the strength and stability of the cement. Calcium oxide contributes to the solidification and hardening effects. Customers can choose the appropriate cement based on their requirements for high temperatures and strength.
Fineness
Fineness refers to the size of the particles in refractory cement materials. The fineness of cement affects bonding performance, hydration reactions, and strength. When the particle size is finer, there are fewer gaps in the refractory mix. This results in higher density and strength. With a larger surface area, hydration effects and strength are enhanced. When selecting cement, we provide detailed guidance to our customers.
Setting Time
Setting time refers to the time required for cement to mix with water and fully cure. It includes initial setting time and final setting time. The final setting time of refractory cement provided by Kerui Refractory is between 90-360 minutes. Quick-drying cement aids in construction and industrial building and repairs.
