<p>The invention relates to a method of deactivating granules containing at least calcium oxide present in slag material by bringing the slag material, optionally in a comminuted form, into contact with water in the presence of a substance which prevents the formation of a thin layer which retards water permeation around the said granules. The deactivation is expediently carried out at elevated temperature, preferably at a temperature of at least 70 DEG C and a relative humidity of at least 80%. The particle size of the slag material preferably is from 1 to 50 mm.</p> |
