Portland cement is essentially the ground product of Portland cement clinker. In some rare cases the clinker can be milled alone to produce a usable cement, however, as discussed below, cement requires the presence of sulfate (SO 3 ) in order to control the setting characteristics and if this is not present in sufficient quantities in the cement clinker then an addition of sulfate-bearing material is required.Consigue una cotización
