Amorphous determination in calcium sulfoaluminate materials by external and internal methods
(ICE Publishing, 2014)
External standard methodology has been successfully applied to quantify the known amounts of amorphous component that are increasingly added to cement-related materials. The consistency and accuracy of the methodology were ...
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 ...
X-ray powder diffraction applied to cement related phases: in-situ and high resolution applications
XRPD is a powerful tool for material characterization in general, and for in-situ studies of chemical processes in particular. The use of an intense X-ray source, .i.e. synchrotron X-rays, coupled with fast X-ray detection ...
