Work Item

ASTM WK94277

New Test Method for Determination of Alkali Release from Cementitious Materials

1. Scope

This is a test method to determine the available alkalies from entire cementitious system (OPC or PLC + SCMs) that could contribute to alkali-silica reaction.

Keywords

alkali

Rationale

This standard is needed to be part of a new approach for preventing alkali-silica reaction in concrete. A new test method work item to develop a standard test to determine the alkali threshold of aggregates has been approved and is in process. This test method provides the second piece of information needed for this new approach.
