Standard Test Method for Potential Expansion of Steel Slag from Hydration Reactions by Autoclave

Importancia y uso:

4.1 This test method provides a procedure for determining the compliance of steel slags and other materials with specifications or applications that limit permissible expansion of base and subbase aggregates containing components subject to hydration.

4.2 This test method can also be used to evaluate the effectiveness of aging or other treatments for reducing the expansive potential of such materials.

4.3 This test method is utilized for dense graded materials passing a 25.0 mm (1 in.) sieve. If it is desired to investigate materials larger than a 25.0 mm (1 in.) sieve, Indiana Test Method ITM 219 should be considered.

4.4 Test results have not been correlated with field performance, and values obtained do not necessarily indicate expansion that may occur in service conditions. The various methods will provide different numerical results due to differences in severity of the procedures.
