Effect of different retarders on the hydration of calcium sulfoaluminate eco-cement pastes
The manufacture of Calcium SulfoAluminate (CSA) cements is more environmentally friendly than that of OPC  as their production releases up to 40% less CO2 than the latter. The main performances of CSA cements are fast ...
Effect of calcium sulfate source on the hydration of calcium sulfoaluminate eco-cement
The availability of cements, including eco-cements, with tailored mechanical properties is very important for special applications in the building industry. Here we report a full study of the hydration of calcium sulfoaluminate ...
Pseudo-cubic crystal structure and phase transition in doped ye'elimite
(ACS publications, 2014)
Sodalites are tridimensional alumino-silicate materials containing cages where loosely bonded anions are located. Ye'elimite, Ca4[Al6O12]SO4, is outstanding as an aluminate sodalite with a flexible framework accepting ...
Rietveld quantitative phase analysis with molybdenum radiation
(Cambridge Core, 2014)
Building materials are very complex samples of worldwide importance; hence quantitative knowledge of their mineralogical composition is necessary to predict performances. Rietveld quantitative phase analysis (RQPA) allows ...
Hydration mechanisms of two polymorphs of synthetic ye'elimite
Ye'elimite is the main phase in calcium sulfoaluminate cements and also a key phase in sulfobelite cements. However, its hydrationmechanismis not well understood. Here we reported newdata on the hydration behavior of ...
