The tests of concrete microbar samples were divided into three series for concrete microbar test: single effect of freezing-thawing cycle, single effect of accelerated alkali-silica reaction, and interaction effect of alkali-silica reaction and freezing-thawing cycle. 小混凝土法试验将小混凝土柱试件分为冻融循环单一作用、快速碱-硅酸反应单一作用、冻融循环和快速碱-硅酸反应交互作用三个系列。
