Beschreibung
Zusammenfassung:	The invention discloses a composite cementitious material and a preparation method thereof; the composite cementitious material comprises portland cement, fly ash, steel slag powder, granulated blast furnace slag, a volcanic ash mixed material, silicon ash, a sulfate activator, an alkali activator, an additive, and the like, and is prepared by processes such as mixed-grinding, stirring, etc. The advantage is that the composite cementitious material has high early strength, frost resistance, seepage resistance, and no pollution, can improve the stability of concrete, has low cost, and simple process, and can be used as a cementitious binder of high-performance concrete.
