ASTM C454- Standard Test Method for Disintegration of Carbon Refractories by Alkali
Description:
Significance and Use
2.1 The disintegration of carbon refractories by alkali attack at elevated temperatures is an important consideration in using these materials for certain applications. Disruption of carbon refractories in the test is sensitive to a number of variables, including alkali concentration, temperature, and the presence of water vapor. The procedure is suitable for guidance in product development and for relative comparisons in application work such as in blast furnace service.
Scope
1.1 This test method covers the behavior of carbon refractories when subjected to the action of an alkali at an elevated temperature. This destructive condition as encountered in service is accelerated in the test to show in a short time the probable behavior of the carbon refractory during use.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
