Application of Calcium Aluminate Cement
- Raw Materials for Unshaped Refractory Products
It is common to use CAC cement as raw material for refractory castables, refractory mortars, refractory ramming materials and other products. Because after adding refractory cement, the moisture in the castable can be quickly removed and a smooth surface can be formed after hardening;
- Rapid Repair Work
CA70S, CA80S high alumina cement have good fluidity and a long construction time. Suitable for applications in summer and other high temperature environments. CA70W has a faster setting speed and stronger early strength, suitable for winter or other low temperature environments, or kilns that require rapid construction and repair.
- Other High Temperature Industries
Refractory cement can be directly used to build the lining of high temperature kilns and equipment, such as blast furnaces, electric furnaces, steel mills, chemical equipment, boilers, etc. This product has a very wide range of uses.
Features of Calcium Alumina Cement
Good High Temperature Resistance
The main feature of calcium alumina cement is that it can maintain stable performance in high temperature environment, and can usually withstand high temperature up to 1500℃.
Good Chemical Corrosion Resistance
Because calcium aluminate cement contains a large amount of chemical components such as aluminum oxide and silicon oxide, it can resist the erosion of strong corrosive substances such as acids and alkalis.
High Compressive Strength
The fire cement has high compressive strength and can withstand great pressure. Therefore, it has wide application in construction, metallurgy and other industries. Now visit how it performs great on Kerui LinkedIn.
Strong Plasticity
Refractory cement has good processing performance. It’s a kind of ideal material to make refractory products of various shapes and sizes through different processing techniques.
Good Sealing and Repair Performance
Refractory cement has good adhesion and filling properties. It has good performance in sealing cracks, holes and joints in furnaces or equipment. You can also use it to repair and restore damaged refractory surfaces to extend their service life.
Difference Between Calcium Aluminate Cement and Ordinary Cement
- Raw materials: the main raw materials of calcium alumina cement are bauxite and calcium aluminate (commonly known as limestone); while the main materials of ordinary cement are calcium aluminate (commonly known as limestone) and calcium silicate;
- High temperature resistance: refractory cement can be used continuously at high temperatures up to 1000℃;
- Different use environments: aluminate cement can maintain good performance in working environments with strong mechanical strength and severe chemical corrosion, while ordinary construction cement cannot;
- Different hardening times: the calcium alumina cement only needs 24 to 72 hours to reach full strength, while ordinary product takes about 10 to 20 days;
