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.<\/p>\n

This method is applicable only to liming materials with a maximum particle size of 6,3 mm determined in accordance with ISO 20977.<\/p>\n

\n

NOTE For marble dolomite (BET procedure as defined in ISO 9277 below 500 m2<\/sup>\/kg), see EN 14984.<\/p>\n<\/blockquote>\n
