This test method covers the determination of the susceptibility of an aggregate or combination of an aggregate with pozzolan or slag for participation in expansive alkali-silica reaction by measurement of length change of concrete prisms. The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. When combined standards are cited, the selection of measurement system is at the user’s discretion subject to the applicable requirements.
WJE laboratories are accredited by AASHTO (R18), ANAB (ISO/IEC 17025), and Illinois DOT to perform testing standard ASTM C1293 for Determination of Length Change of Concrete Due to Alkali-Silica Reaction.
