About High Alumina Cement

High Alumina Cement

High Alumina Cement (HAC) is also known as Calcium Aluminate Cement (CAC). It is widely used in production of monolithic refractories. It is also used for special construction applications, steel plants, etc. It is composed of calcium aluminates, unlike Portland cement which is composed of calcium silicates. Itis manufactured from limestone or chalk and bauxite. We are a leading Manufacture, Supplier and Exporter of Best Quality High Alumina Cement or Calcium Aluminate Cement as per the customer requirements.

HAC was prone to a crystalline re-arrangement which could result in reduced strength and also vulnerability to chemical attack when exposed to water for long periods. It was widely used in structural concrete such as pre-cast beams. as a protective liner against microbial corrosion such as in sewer infrastructure. High alumina cement offered by CMS INDUSTRIES is known for its chemical and physical properties inthe foreign markets.

Superior High Alumina Formulation

Manufactured with high purity alumina (50%-60%), this cement delivers outstanding mechanical and thermal properties. Its high initial strength, low thermal conductivity, and minimal expansion on heating make it suitable for demanding refractory applications in furnaces and kilns.

Engineered for Extreme Conditions

High Alumina Cement is designed to perform under severe environments, with a maximum service temperature up to 1600C. It provides excellent resistance against alkali attack, corrosion, and fire, ensuring long-term durability and safety for industrial installations.

Convenient Packaging and Shelf Life

Packed in 25 kg and 50 kg bags, this cement maintains a shelf life of 6-12 months if stored in dry, sealed conditions. Its fine powder consistency allows for easy mixing and application, supporting efficient construction and repair processes.

FAQ's of High Alumina Cement:

Q: How should High Alumina Cement be stored to maintain its shelf life?

A: To ensure a shelf life of 6-12 months, High Alumina Cement should be kept in a dry place and tightly sealed to prevent moisture ingress and degradation.

Q: What is the recommended curing process for optimum strength development?

A: For best results and maximum strength, the cement should be cured under moist conditions after application to allow proper hydration and minimize premature drying.

Q: When can high compressive strength be expected after application?

A: High Alumina Cement achieves a compressive strength of 30-50 MPa within 24 hours of application, making it suitable for rapid construction schedules.

Q: Where is High Alumina Cement commonly used?

A: High Alumina Cement is primarily used in refractory constructions, such as furnace linings, kiln furniture, and other high-temperature installations due to its superior thermal and chemical stability.

Q: What are the benefits of using High Alumina Cement in high-temperature applications?

A: This cement offers excellent fire resistance, negligible expansion on heating, superior corrosion and alkali resistance, and maintains dimensional stability, making it ideal for demanding heat-intensive environments.
