| Abstract: | The self destruction phenomena of refractory castable bonded with hydrated alumina cement occurred in industry were analyzed focusing on the separation on the surface of castables. The results show that the carbonation, sulphation owing to acid gases (e.g. CO 2 ? SO 2 ?H 2 S) in the air and separation of some soluble species from the interior of the castable to its surface are the reason of self destruction. Some factors such as aging condition, quality of the adding water of the castables must be considered so as to prevent the destruction of castables bonded with high alumina cement. |
