Aluminate cement also named high alumina cement, caclium aluminate
cement, refractory cement .Our refractory cement divide into normal
grade and high strenght grade aluminate cement.Normal grade
aluminate cement is widely used in refractory castable, gun-mix
refractory etc unshaded refractory materials,shuc as refractory
castable for boiler wall,beam.Normal grade aluminate cement data as
follows:Grade NameNormal grade CA50Type
