Aluminum Hydroxide Gel Characterization within a Calcium Aluminate Cement Paste by Combined Pair Distribution Function and Rietveld Analyses
(Elsevier, 2017-06)
There are many commercially important multiphase materials which contain amorphous phases, such as cement
pastes, porcelains, glass-ceramics or pharmaceutical compounds. However, the analysis of amorphous phase(s)
within ...
Rietveld quantitative phase analysis of yeelimite-containing cements
(Karen Scrivener, 2012)
Yeelimite-containing cements are attracting attention for their tailored properties. Calcium sulfoaluminate, CSA, cements have high contents of Yeelimite and they are used for special applications. Belite calcium sulfoaluminate, ...
Local structure and Ca/Si ratio in C-S-H gels from hydration of blends of tricalcium silicate and silica fume
(Elsevier, 2021-03)
At the microscale, C-S-H gels from alite, or neat Portland cements, has a Ca/Si ratio close to 1.80. At the nanoscale, C-S-H is described by a defective tobermorite structure which allows a maximum Ca/Si ratio close to ...
