摘要： The present invention relates to a reactive binder mixture comprising, based on the total dry matter, 10 to 40 wt. % hydraulic cement, 40 to 80 wt.% calcium sulphate hemihydrate, and 0,5 to 35 wt. % silica source material comprising a monomeric, oligomeric or polymeric silicate-based material comprising up to 15×10 6 repeating units, similar or different, of formula I:

        [-O-SiR 1 3 ]     (I)

wherein each R 1 is independently selected from alkyl, alkoxy, alkenyloxy, phenoxy, acetoxy, hydroxyl and a single bond.
The silica source material may further comprise silica fume, metakaolin and/or fly ash.

摘要： The present invention relates to a reactive binder mixture, comprising, based on the total dry matter 10 to 40 wt.% hydraulic cement, 40 to 80 wt.% calcium sulphate hemihydrate, 2 to 35 wt.% pozzolanic material, and 0.1 to 5 wt.% booster additive selected from soluble alkaline earth salts, strong acids and combinations thereof. The pozzolanic material may preferably be selected from fly ash, metakaolin or silica fume. The soluble alkaline earth salt may preferably be selected from magnesium sulfate, magnesium nitrate and magnesium chloride. The strong acid may preferably be selected from chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, perchloric acid, nitric acid and sulfuric acid.
