(Main)Carbonate and silicate liming materials - Determination of reactivity - Potentiometric titration method with hydrochloric acid
General Information
- Abstract
This European Standard specifies a method for the determination of the speed and effectiveness of the neutralising potential of calcium carbonate, calcium magnesium carbonate and calcium magnesium silicate liming materials by potentiometric titration with hydrochloric acid.
This method is applicable only to liming materials with a maximum particle size of 6,3 mm.
NOTE The type of liming material should be identified according to EN 14069 and the particle size should be determined according to EN 12948.
