Refractory Cement

Refractory cement refers to a type of cementitious material that is fast hardening, high-strength, heat-resistant, and corrosion-resistant. Its main characteristics include high early strength, high temperature resistance, and corrosion resistance.

High alumina cement is a hydrated cementitious material that is mainly composed of calcium aluminate and contains about 50% alumina. Also known as refractory cement. The professional name is aluminate cement.

Refractory Cement Characteristic

Early strength characteristics: its early strength increase rate is far more than rapid hardening Portland cement, which is suitable for emergency repair projects, but its late strength will be reduced, and its use is limited in structural engineering.
High hydration heat: Early cement has a high heat release during hardening, and compared to Portland cement of the same grade, it can release 70-80% of the total hydration heat in just one day. Due to several types of heat release, it is suitable for low-temperature curing of concrete engineering.
Strong resistance to sulfate attack: during hydration, free calcium hydroxide is not separated, but aluminum hydroxide gel is generated, forming a protective film on the surface of particles. The corrosion resistance decreases during the later stage of crystal transformation.
Good high-temperature resistance: High alumina cement can be used as a bonding material for heat-resistant concrete and configured as heat-resistant concrete.

Refractory Cement Application

1 Refractory cement is mainly used for urgent construction projects, such as pressure prevention, roads, and special repair projects, and can also be used for winter construction projects

2 Preparation of amorphous refractory materials

3 Furnace Linings: Refractory cement is commonly used to line industrial furnaces, as it can withstand the high temperatures produced by furnaces.

4 Foundries: Refractory cement is used in foundries, where it is used to line furnaces used to melt metals.
