Factors Affecting High Alumina Cement Price

Composition of High Alumina Cement

High alumina refractory cement is a kind of refractory mainly composed of Calcium aluminates compound. It is manufactured by heating a mixture of limestone and bauxite to a high temperature, which results in the formation of calcium aluminate clinker. The higher the aluminum content in high alumina refractory cement, the higher its price will be.

In addition to these calcium aluminates compounds, the cement may also contain a small amount of other mineral components, such as silicate and ferrite. These components can affect the performance of cement, such as setting time and strength development. And the amount of these ingredients added also affects its price.

CA70 is a type of high alumina refractory cement with an alumina content of around 70%. This refractory cement has higher ultimate strength and better durability than CA50, but its early strength development is slower. It is commonly used in applications where high strength and durability are required, such as in the construction of precast concrete elements and in refractory applications.

CA80 is the alumina refractory cement with an alumina content of about 80%. It has the highest ultimate strength and best durability of the commonly used high-alumina cement. Its early strength development is slower than that of CA50 but faster than that of CA70. CA80 is commonly used in applications where high strength and durability are critical, such as in the construction industries and in high-temperature refractory applications.

Properties of High Alumina Cements

The performance of the reafrctory cement directly influences the price of the cement. Refractory material manufacturers high-quality cement with excellent properties, and has a higher price in the market. Generally, high-quality  refractory cement has the following properties:

  • High-temperature Resistance: The cement can withstand high temperatures without losing itsintegrity, which makes it suitable for use in high-temp applications.
  • Low Permeability: The low permeability of high alumina cement reduces the risk of water seepage and damage to concrete structures in harsh environments.
  • Strong Chemical Resistance: The cement has a high resistance to chemical attack, which makes it suitable for applications exposed to corrosive environments.
  • Rapid Strength Development: High alumina cement has rapid strength development. This property allows for quick turnaround time in construction projects.
  • High Compressive Strength: This cement has strong compressive strength and is suitable for high-strength applications, such as high-temp buildings.
  • High Durability: The cements are highly durable to withstand harsh environmental conditions. It is suitable for structures operating in corrosive chemical environments.
