Minerals of expansive and non-shrinkage sulfomineral cements
MATEC Web of Conferences, 2017 Usually to obtain expansive cements sulfoaluminate clinker or mix aluminate clinker with calcium sulfates (gypsum, hemihydrate, anhydrate) are used. For these cements ettringite is an important hydration product and kinetic reaction of this phase plays ...

Limestone reaction in calcium aluminate cement–calcium sulfate systems [PDF]
Cement and Concrete Research, 2015 This paper reports a study of ternary blends composed of calcium aluminate cement, calcium sulfate hemihydrate and limestone. Compressive strength tests and hydration kinetics were studied as a function of limestone and calcium sulfate content. The phase evolution and the total porosity were followed and compared to thermodynamic simulation to ...

Spinel Aluminate‐Based Heterojunctions as Photocatalyst: A Review
ChemistryOpen, EarlyView.Spinel aluminates (MAl2O4; M = Zn, Mg, Ca, Sr) serve as robust platforms for designing heterojunction photocatalysts. Their stable lattices, tunable band structures, and efficient charge transport enable improved light‐driven carrier separation, significantly enhancing pollutant degradation efficiency in advanced photocatalytic systems.
