Several Types of High Temperature Resistant Cement

High-temperature resistant cement has various types according to its composition, use, and performance. The following are several common types of high-temperature resistant cement and their characteristics:

1. High Alumina Cement

Features: Excellent high-temperature resistance and corrosion resistance.
Classification: According to its aluminum oxygen ratio (Al2O3/SiO2), high alumina cement can be divided into four types: CA-50, CA-60, CA-70, and CA-80, among which CA-80 high alumina cement is the highest type.
Application: Widely used in high-temperature kilns, metallurgy, building materials, and other fields.

2. Portland Cement

Features: Good high-temperature stability and acid and alkali corrosion resistance.
Classification: According to its furnace temperature, Portland cement can be divided into three types: P-type, M-type, and K-type. Among them, P-type Portland cement has the highest refractoriness, which can reach more than 1700℃.
Application: Usually used in occasions that need to withstand high-temperature environments.

3. Refractory Mortar

Features: Strong bonding with various materials, good high-temperature resistance, corrosion resistance, and earthquake resistance.
Classification: According to its use and hardening method, refractory mortar can be divided into conventional refractory mortar, self-hardening refractory mortar amino resin self-hardening refractory mortar, and other models.
Application: It can be used in refractory lining, thermal insulation concrete, heat-resistant concrete, and other fields.

4. Aluminate Refractory Cement

Features: High early strength and refractoriness close to low calcium aluminate refractory cement, but the use is the same.
Preparation: It is usually made by mixing and grinding 4 parts (by mass) of low calcium aluminate refractory cement clinker and 1 part of high aluminum cement clinker.
Application: It plays a key role in the preparation of refractory concrete or refractory mortar.

5. Low Calcium Aluminate Refractory Cement

Features: It is made of high-quality bauxite and limestone as the main raw materials, sintered and ground, and has good refractory performance.
Application: It can be used in combination with other refractory materials to make high-temperature-resistant products.

The above is a brief introduction to several common types of high-temperature resistant cement, their characteristics, and application areas. The selection of these cement types depends on the specific use environment and requirements.
