标准摘要
[中文适用范围]: 本文件规定了测定碳酸钙和碳酸钙镁石灰材料反应性的方法。 它通过柠檬酸自动滴定来评估其中和潜力的速度和有效性。 该方法仅适用于根据 ISO 20977 测定的最大粒径为 6.3 mm 的石灰材料。 注:对于大理石白云石(ISO 9277 中定义的 500 m2/kg 以下的 BET 程序),请参见 EN 14984。 [外文原描述]: This document specifies a method for determining the reactivity of calcium carbonate and calcium magnesium carbonate liming materials. It assesses the speed and effectiveness of their neutralising potential by automatic titration with citric acid. This method is applicable only to liming materials with a maximum particle size of 6,3 mm determined in accordance with ISO 20977. NOTE For marble dolomite (BET procedure as defined in ISO 9277 below 500 m2/kg), see EN 14984.
