Phạm vi áp dụng / Scope of standard

This test method covers chemical determination of the reactivity of an as-received fine and coarse aggregate in terms of measuring composite activation energy of alkali-silica reaction (ASR), where aggregate reacts with an alkaline solution having chemistry similar to the pore solution chemistry of a conventional portland cement concrete.
