Structure of stratlingite and effect of hydration methodology on microstructure [PDF]

, 2015
Stratlingite, Ca4Al2(OH)12[AlSi(OH)8]2•2H2O, is an AFm phase which appears as hydration product of aluminum-rich cements. These binders may be calcium aluminate cements, calcium sulfoaluminate cements and also Belite Calcium Sulfo-Aluminate (BCSA ...

3D-Mesomechanical analysis of external sulfate attack in concrete [PDF]

, 2017
The present study focuses on degradation of concrete by external sulfate attack. The numerical model developed by the MECMAT/UPC group, incorporates coupled C-M analysis using a meso-mechanical approach with discrete cracking, using the MEF and zero ...

Chemical shrinkage of hydrating calcium aluminate cement

, 2010
Hydraulic hardening of calcium aluminate cement (CAC) is primarily due to the hydration of mono-calciumaluminate, in idealized pure form CaAl2O4 (CA), but other compounds also participate in the hydration process especially at higher temperatures and in long term development.

Microcalorimetric study on calcium aluminate cement hydration

, 2008
Calcium aluminate cement (CAC) is very versatile special cement used for specific applications. During the hydration of CAC a large quantity of heat is liberated within one day that causes a considerable increase of temperature in material. This paper examines the hydration of three samples (A, B and aged B) of commercial CAC ISTRA 40 (producer: Istra ...

Raman spectroscopy of cements: Problems and possibilities

, 2011
Until recently there has been a common held misconception that Raman spectroscopy of cements is not possible, or at least so inconvenient as to make it impracticable.
