摘要
江南燧石和红水河燧石具有不同的碱活性，但其α石英在晶体结构上没有明显的差异。两种燧石碱活性的不同是由于江南燧石含有沥青质，沥青质的存在抑制了碱－集料反应的进行。
The alkali reactivity of Jiangnan chert and Hongshuihe chert is not the same, though the crystal structures of a-quartz from these two kinds of chert have no obvious difference. The distinction in the alkali reactivity of the two kinds of chert is found to be due to the fact that Jiangnan chert contains asphalt which inhibits the alkali—aggregate reaction .
