ASTM C454

Standard Test Method for Disintegration of Carbon Refractories by Alkali

Ten 2" cube specimens are required by ASTM. A 1" hole is drilled into the face of each specimen and filled with 8 gm of Potassium Carbonate. The effects of being fired at 1750°F for 5 hours are determined visually.

$960 per test of 10 specimens

Significance and Use

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.

 

1. 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.
