JIS A 1146 – Method of test for alkali-silica reactivity of aggregates by mortar-bar method

JIS A 1146:2017 specifies the test method (hereafter referred to as mortar-bar method) to judge hte alkali-silica reactivity of aggregates by measuring the length change of mortar-bar. This Standard is not applicable to artificial light-weight aggregates (coarse or fine). In addition, the judgement in clause 16 is not applicable to aggregates taken from hardened concrete.

The comparison table between previous and current editions of this Standard on technically significant revisions is given in Annex A.
