Beschreibung
Zusammenfassung:	A cement additive with high resistance to sulfur is proportionally prepared from the water-quenched slags of blast furnace, the shrinkage reducing component consisting of alkylenediol or polyoxyalkylene glycol and wollastonite, and the modifier consisting of polycarboxylic acid type super-disperser and triethanolamine. It can resist against the corrosion of multiple sulfates.
