High Alumina Cement is an excellent unshaped refractory materials for sale in RS Factory. The main chemical composition of High Alumina Cement includes calcium aluminate, plus about 50% of the alumina. High Alumina Cement is widely used in the construction industry, refractory industry, engineering, and food processing industry, etc.
High alumina cement specification can be reflected from the physical and chemical index below.

High Alumina Cement Composition
High aluminous cement is called bauxite cement before. It is a kind of hydraulic binder, being produced after the calcining and grinding with the bauxite and limestone as the raw material, so it is also called calcium aluminate cement.
High Alumina Cement Properties
High alumina cement properties: alumina cement has advantages of fast coagulation, high initial strength, good corrosion resistance to sulfate, good resistance to high temperature, and biological acid erosion.
Compositions: Bauxite and limestone
Properties
- High initial strength
- Sulfate corrosion resistance, and biological acid erosion
- High temperature resistance, and fast coagulation,etc.
High Alumina Cement Uses
High Alumina Cement is applied in the emergency repair project and low temperature concrete engineering. As a kind of binder, aluminate cement can be used as heat resistant concrete cementation material for refractory castable or refractory concrete, configured to heat resistant concrete. We call such material high alumina cement concrete.
High alumina cement uses are strongly reflected in different areas. It is the preparation of monolithic refractories and special cement such as gypsum alumina expansive cement and self-stressing cement. In addition, it is used in the scrambling and repairing project, constructions in winter, engineering of sulfate-resistance, sewage pipe manufacture and some food processing factory ground.
Applications
- Emergency repair project
- Low temperature concrete engineering, etc.
High Alumina Cement manufacturing methods
- Rotary kiln sintering
- Arc furnace melting method
- Reverberatory furnace melting method, etc.
High Alumina Cement Problems
In the process of installing the high alumina cement , some attentions should be paid to, or some problems may arise.
Attentions
- It can’t be mixed with lime and Portland cement, so the mixing equipment must be cleaned.
- It can’t be used for projects that direct contact the alkaline solution.
- It is not used in mass concrete, and it can’t contact the non-hardened Portland cement.
- Without the test, it can’t be added to any additional content.
