目前大家一致认为碱骨料反应与每立米混凝土中碱含量密切相关。总碱量愈高碱骨料反应愈严重。一般认为碱含量小于3kg/m~3(以等当量Na_2O计,下同)问题不大。南非则以小于1.8kg/m~3为安全的,1.8～3.3kg/m~3为具有可疑危害的,大于3.8kg/m~3为有害的。也有个别资料谈到有的活性骨料要总碱量超过5kg/m~3才是不安全的。应该注意到这里讨论的分界线一般均 At present, it is generally agreed that the alkaline aggregate reaction is closely related to the alkali content in each concrete. The higher the total alkali content, the more severe the reaction of alkali aggregates. It is generally believed that the alkali content is less than 3kg/m 3 (equivalent to Na 2 O, the same below) is not a problem. South Africa is less than 1.8kg/m 3 safe, 1.8 to 3.3kg/m 3 is suspicious, and more than 3.8kg/m 3 is harmful. There are also individual reports that some of the active aggregates are not safe if the total alkali content exceeds 5 kg/m3. It should be noted that the dividing lines discussed here are generally
