JIS A 1145:2017规定了化学试验方法（以下简称化学方法），以相对迅速地判断混凝土用骨料的碱硅反应性。本标准不适用于人造轻骨料（粗骨料或细骨料）。此外，第11条中的判断不适用于取自硬化混凝土的骨料。本试验方法旨在判断碱硅反应性；可能显示其他类型反应的骨料需要进行岩相检查。附录A中给出了本标准之前版本和当前版本在技术重大修订方面的对比表。

JIS A 1145:2017 specifies the chemical test method (hereafter referred to as chemical method) to judge, relatively promptly, the reactivity of alkali-silica of aggregates to be used for concrete. This Standard is not applicable to artificial lightweight aggregates (coarse or fine). In addition, the judgement in clause 11 is not applicable to aggregates taken from hardened concrete.This test method is intended to judge alkali-silica reactivity; aggregates which could show other types of reaction need to be subject to petrographic examination.The comparison table between previous and current editions of this Standard on technically significant revisions is given in Annex A.
