Special castables engineered against cement alkali attack and chemical acid/alkali corrosion.
Alkali-resistant grades counter alkali-vapor condensation in cement kilns, while acid-resistant grades serve chemical stacks, ducts and acid-gas treatment. Choose by alkali/acid type and temperature for cement and petrochemical/environmental services.
