Ferric aluminate cement has diverse applications. Its excellent high – temperature resistance makes it ideal for high – temperature resistant engineering like blast furnace and kiln linings. Its rapid hardening and high early – strength suit emergency repair. It’s used in projects needing high corrosion resistance in salty or acidic areas. It also meets specific needs in special concretes, mortars, and is sometimes applied in decorative building materials for good workability and decorative effects.
