Alumina and alumina-silicate castable refractories are produced to yield property characteristics commensurate with different end use properties. Volume stability, modulus of rupture, bulk density, and lime content have become useful measures to distinguish various alumina and alumina-silicate castable formulations for initial fitness for service. This classification is considered useful for purchase specifications and for quality control.

1. Scope

1.1 This classification covers alumina and alumina-silicate castable refractories that, when tempered with water, will develop structural strength by chemical action.

1.2 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
