| Zusammenfassung: | The hydration process and the paste structureof a new cementitious mineral 3CaO·3Al2O3·SrSO4 have beeninvestigated in the presence of different sulphates.It is difficult to form hydrates with SrSO4,but the paste is toughened greatly by SrSO4 microcrystal precipitates and very high strength is ob-tained.A quantity of expansive ettringite is formed in the pres-ence of gypsum.That makes porosity of paste increase and strength decrease. |
